So if the ranger monk splash is overpowered... what do you do about it?

[Borror0]

for ac they would have to have a very high dex to begin with for this to matter, means poor every thing else.

Wrong. Hafling 10/17/14/9/17/8 could a way to do it.

Dex, Con and Wis are all that matter on that build anyway. What is "everything else"?

to get a good ac you need to have ce, ce drops EVERY time you cast a spell.

Eh, no, since you are not melee good AC is not the same.

You give up sp and if you go for evasion you miss out on the highest levels of spells currently in the game

Miss out on...what exactly? Nothing most will care about. Plus, by level 20, you're missing out on nothing.

You're only missing out on SP, again, your request was "best at AC".

DPS and a lot of it, which I would have thought is a major concern.

Prove it. I doubt it, seriously.

HP and a lot of it

False and utterly wrong. Yes, I had to say both, because that's how inaccurate that is.

Can you give me an example where one was based on removal or limiting of a class ability [not enhancement mind you]?

I don't understand the question.
