Also, if a creature makes its save versus a spell where the save is to negate all effect, it's immune to that caster's castings of that spell for ten minutes. 24H is asinine, and all those immunities, from Trumpet Archons et. at., should be reduced to the same ten minute span.
Yeah that's good too. Today I was mentally comparing Warhammer's "invulnerability saves" to saves in D&D.
It would be a good idea to provide dedicated warriors the ability to absolutely resist a certain number of attacks each round or combat, as well as the 'speed types' such as Rogue and Bard to outright dodge and charge farther and faster than, say, Dimension Door. It's supernatural qualities, sure, and somewhat bordering on animu levels of unreal combat.
Wizard casts Imprison
Fighter fails save, uses Deny as an Immediate Action.
Deny roll passes.
Imprison won't work on Fighter until the next encounter.. or day.
This talk of spell revision is always going on, every forum, all the time. As long as D&D exists I really don't think we'll see an end of the "Let's fix spellcasting!" proposals.
4e seems to have tackled most of that overpowered crap but even now they are unraveling it with every further splatbook.
