Would it be something like this:
Base BAB + (
Caster level (max 30) /
3) = 'Polymorph BAB' (capped at 30)
With a function like above, our low BAB pure arcanist could get a BAB of 25. While the more gishy transmuter would end up at BAB of 30.
Or would it be something like this:

With a function like above, our low BAB pure arcanist could get BAB of 21+, which is enough to get that fifth attack per round. While the more gishy transmuter would end at BAB of 26+, which would be enough to get that sixth attack per round.
Divine casters like Spirit Shaman would be on par with gishy transmuters, BAB-wise.
Anyhow, I am not entirely sure about this BAB increasement thing, and I would be against it if it turns a non-gish transmuter into a better or equal melee character than a gishy transmuter. After all, if you can get the same or higher BAB with just some Sorcerer/Archmage/Arcane Scholar metamagic and spell control build - or even with that Sorcerer/Shadow Adept/Blood Magus/Arch Mage DC build - what would be the point of the PRC classes such as Eldritch Knight, Dragon Slayer, Bladesinger, etc?

Polymorph duration will not be reduced. Currently its 1min/level and I think about raising it to 10min or 1 hour/level.
Alright, but it does raise a question of how these new Polymorph Self forms compare to our current Shapechange forms. Are these new forms closer to old Polymorph Self or the old Shapechange forms? How about after applying the Greater Magic Weapon spell?
If these new forms are somewhat comparable to the current Shapechange forms, then I do not think the arcane transmuters will be negatively affected by the shorter Shapechange spell duration. If they team up, they can just use Polymorph Self and tag along as they already do with current Shapechange. It will eat some potential spell slots from Elemental Shield, etc, but I think it is a cost that would be livable. Not to mention that they could cast Polymorph Self as a quickened spell.
But that is this topic from the point of view of arcane transmuters.
Divine casters do not have access to Polymorph Self beyond Ranger's spell book. (Ranger Shifters should be possible too.)
Druids have their wildshape, and their spell casting in wildshape, and eventual Dragonshape and therefore they do not really have any real need to cast Shapechange.
Thus when it comes to Shapechange and divine casters, where else to look than Spirit Shamans and the earliest point they can gain access to their Shapechange spell at level 18.
Spirit Shamans are a medium BAB progression class, and if they start out with something like 16 strength they should be able to reach level 18 with relative ease. All they need to do is get some +3 or better equipment while they level, and buff up with Bull's Strength, Thorn Skin, Flame Weapon, while spells like Lesser Vigor, Vigor, and Regenerate provide enough healing to tank out the mobs on the server.
If they go for a wisdom based build, then they can get the Zen Archery feat at level 6 and make use of Shortbows and slings thereafter. They can summon things, and use their selection of 'no DC' offensive spells to spice things up.
If they are a charisma based Spirit Shaman/Blackguard or Cleric, well, it is a bit more annoying to level up but fundamentally 13+ base strength for Divine Shield is not that different to starting the game with 16+ strength. What stings most is how ninth level spells get pushed to level 21.
So all in all, it should be possible for a Spirit Shaman to be useful enough outside of the Shapechange spell.
Now, what remains is the Monk/Sacred Fist/Spirit Shaman builds. In stock NWN2, all Shapechange and Polymorph Self forms have their respective 'creature weapons' which are not counted as unarmed. Therefore, using the Shapechange or Polymorph Self spell actually drops the Sacred Fist's AB by -10. If a shape has no weapon, it would be nice if it would get +10 AB to negate that penalty, or something like that.
