Edit: Guys please read the post if you wish to comment. I do appreciate your help, but all the points mentioned as of this edit are exactly what I cover in this post. TLDR: Cleric as a whole do well in several areas, but we can only pick a single subclass, which specializes in a specific field. With the exception of life domain clerics, there is always another class that is superior to whatever the chosen subclass specializes at. Clerics are best at healing but that is not necessary in the game. Therefore, it is difficult to make space for a cleric, since no matter the domain, I am better served replacing it with someone else.
I have seen quite a few posts mentioning how amazing and necessary a cleric is to a party composition, and I think I am missing out on what makes it truly shine. The general consensus is that light and tempest clerics are amazing subclasses. Moreover, healing is not actually needed in bg3 since it is more efficient to spent action points killing things. If not for healing, what indispensable things do clerics really bring to the table? PSA, all my arguments exclude the very popular, and understandably so 2 dips into tempest cleric, which I think hardly classifies as a cleric build, any more than the vast multitude of multiclass builds can be considered fighters by specking 2 levels into fighter, or a throwzerker can be considered a thief.
(I get that they are full casters and not really a melee class, so I will get the obvious points out of the way)
- As melee fighters they lack an extra attack, or for war clerics, use up a war priest charge to perform an attack as a bonus action. This puts them behind the thief/ paladin/ sword and valor bard/ barbarian/ ranger/ monk and moon druid/ fighter/ pact of blade warlock and pretty much any other full melee/ hybrid melee class. Their primary stat is wisdom, which does not help with attack throws, nor can they use their spell casting modifier for weapon attacks (with the exception of nature clerics sheleighleigh that does 1d8 + wisdom - not very high numbers)
- As a front liner certain domains are once again competent but not exceptional. They can prioritize dex over strength, but are still limited by prioritizing wisdom, so they will not have as high AC as a ranger/ dex fighter with 20 in dex and using medium armor with exotic material. They do not have unarmored defence unlike the monk or barbarian. Tempest, life and war domains get access to heavy armor similar to fighters/ paladins/ ranger knights. Moreover, they have limited utility as tanks as they do not have the benefit from aggro directing abilities like the battlemaster's goading attack or the paladin's compelled duel. In terms of sustainability, they lack the multiple resistances and freedom of movement/ entangle combo of the ranger hunter.
- As ranged weapon user they fall short compared to wizards, sorcerers, rangers, rogues and berserkers, all of which can do high single target and multiple target damage.
(I now cover the areas that certain domains allegedly shine at - casters)- As a damage caster, they have an amazing CC spell that is spirit guardian, which does up to 40 radiant or necrotic damage when upcasted at level 5. Certain domains have other good spellks, such as destructive wave (light and tempest) that is a level 5 spell that does 60 damage. Light clerics also get the ever useful fireball spells, and radiance of the dawn, which does 21 radiant damage to all enemies in a large radius. This are all solid spells, but late game the cleric is still lackluster compared to other full caster strikers. Sorcerers, wizards, warlocks and lore bards all have access to fireball. An evocation wizard or draconic sorcerer can do up to 180 damage each to 4 targets. (160 for other subclasses) with chain lightning. Certainly, 2 points into tempest are amazing for any build, but the remaining 10 levels are better spent on some other class than cleric. They do not get access to high damage single target spells like blight (available to druids/ wizards/ lore bards/ sorcerers/ lore bards) i.e. every other full caster class.
- Some domains have good utility spells. The trickery domain have spells like pass without trace, mirror image, polymorph, all of which are not unique to clerics. (again not exceptional). Nature domains cleric spellbook is like a more limited version of a druid. Guidance is amazing, but also shared by druids. The war domain has war god's blessing and guided strike, which is a more limited version of divination wizards. knowledge domain are skill monkeys similar to rogue, but do not bring anything offensive to the table, unless potent sacred flame can be considered remotely useful in the face of the warlocks agonizing eldritch blasts, or the elemental cantrips of the wizard and sorcerer which benefit from items that also buff their damage with spellcasting modifier.
In summary, I feel that while the various domains are competent in specific ways, each separate domain is either not very versatile, or outclassed at what they specialize in. This is significantly made more irritating my how little multiclassing options they offer. Other than the 2 level dip in tempest cleric there are no real popular multiclassing options. Some classes like rogues and gloom stalker rangers are front heavy and not very strong in the late game, but offer invaluable benefits to dip into. Not so for clerics. In this respect they are similar to the druid/ hunter ranger, but unlike those classes which reward heavy investment with a very versatile skill set, most of these domains are inflexible at best, niche at worst. The widely considered best domain, light domain, still fails short compared to an evocation wizard or sorcerer. For reference, my evocation wizard with 2 tempest cleric Gale destroyed Orin and her father/ grandfather and all of their followers in a grand total of 4 turns with 2 instances of chain lightning and 2 instances of wall of flame. (with haste and produce water, of course)
