Crippling strikes only stack up to -8 str if I remember correctly. So there is a cap to what can happen. I would imagine that there would also (or should) be a cap on how much a poison can act. It's not realist but at least it would be a compromise.
This is incorrect. I've taken a 72 strength enemy down to 4. So unless my GM co-tester was lying, it goes as far as you can continue to hit things.
Crippling strike has a built-in catch 22. You need to sneak for it to work. But if you can sneak, then you are most likely ditching out tons of damage anyway, and the monster would go down quickly and the effect would have no time to stack. A non-powerbuild rogue (i.e. not 1342 attacks/round at 2883 AB) would probably need about a minute to ditch in enough attacks (10?).
Looking at the statistics for critical hits , you should take into account that WM characters only have better odds because they spend feats on it to improve it .So unless there is a way for other characters to take feats that make the saves others need to make higher , you should disregard them .You will find that a WM who doesn't infest in strength and feats falls back to the critical range of the weapon they use .So in my case 19-20 for critical hits ( longsword )I don't know what you calculate it to be , but i come on a 19-20 that HAS to be thrown on a 20 sided dice .Nice odds right ?Low HD = low saves = low HP's .High HD = high saves =higher Hp's.The loss of HP's on high lvl's might not be much , but if you only have 30 HP to begin with and you lose 1/3 on EXTRA damage ( possibly per round )then it is substantial.( Especially if it stacks for a few rounds )I'm not sure which character has what high saves , but i know that the will save for fighters is always low ( without specialised gear anyway ) , so i suspect other classes have their lower saves as well.
Jan, arguing the weakness of a weaponmaster is an effort of utter futility. Particularly in the case of the WM class, the only fault of imbalance lies with the player.
So what I'm suggesting is the duration increased, one minute would be perfect
