A caster with Str as his main stat could do more melee damage than a fighter, not that it would be too broken as casters stay back anyways but Str makes less logical sense to cast from than Cha.DoPo said:Speaking of 3.X, then
- Strength making casters better at melee? So what - they can be better melee fighters anyway with spells.
- Dexterity makes them "not glass cannons" is quite overselling it - a high dex character can still get hit and receive a lot of damage. Besides, spellcasters already have spells that let them stack AC - if avoiding damage is that much of an issue, then they already achieve that.
- Constitution makes them more tanky? Uh, yeah - incidentally wizards are encouraged to pick con to put a lot of points to. It's actually comical - the scrawny wizards are paragons of healthy, while big buff fighter classes aren't. It's because wizards lack HP/Fortitude, so to make up for it, they can get high con, while buff classes already have high HP/fortitude, thus they can get away with less con than wizards.
The system is fundamentally broken to begin with, but even those aren't good reasons to make casters not use those stats. For example, if you limit the amount of Dex contributing to AC which is a mechanic already in the game (but doesn't apply to casters...because reasons?) suddenly solves them being "not glass cannons". Want to have them not be good at melee? Well, leaving spells aside, having shit BAB already does that - oh no, that caster guy is coming at me and he is going to whack me...once, while his fighter buddy comes and hits me several times. So, these aren't actually reasons for casters not using those stats for spells - it's a side effect of the system.
The real reason they are not using those stats is because...they've never used them. D&D has a bit of a shit design philosophy where they carry over stuff from earlier editions almost wholesale without much regards for how the current system works. Hey, do you know the spell Meteor Swarm [http://www.d20srd.org/srd/spells/meteorSwarm.htm]? It's a level 9 spell and it's quite crap overall considering it's top tier. Do you know why it's top tier? Because it was top tier in AD&D...however, due to the difference in the overall systems, it was much better there than in 3.5, yet it works very similarly in both.
Dex would be horribly broken for casting. AC is pretty damn important for %chance of being hit or not. Why not just give everyone an AC of 40, that's not broken because you can still get hit, try telling a DM that. I had sorcerer with 32 Cha around level 15, just think if that was Dex, that's a +11 AC bonus right there. Then, you could stack spell AC on top of that like you said.
Wizards are encouraged to use Con as their SECONDARY stat, maybe get it up to 14 and get a couple extra HP per level. If Con was a casting stat, bare minimum a caster is going to have at least 20 for their casting stat at level 1, that's 5 HP bonus per level minimum with that going up as they level.
