It really is the stat drains though. I have cleared significant portions of a GUV in melee (Pally with Justifier, Preserver, Protector & BoW, so you know if it was hard...) and with a mindcrafter (lot easier on mindcrafter, actually), and lich kings are simply brutal beyond belief (also I saw gutt "try"* to clear one once, also on a Justifier Pally). The confusion is a huge problem, but that's very, very, very doable with the right preparations (high Wi, water orb, doubling/tripling up -Conf). After a few stat drains in the wrong place, though, you start having to triple & quadruple up on -Conf, and eventually it's just kind of hopeless. Not to mention what they're doing to your non-Wi stats--you have to drop most of your things so you won't be overburdened & are less effective in bashing their heads in, you start losing lots of HP (& possibly PV), your speed & DV take a hit...it's a no-win situation. And that's not even mentioning the summons.
I don't think this is really making melee user's lives easier, at least as far as I have piggybacked on the suggestion (which has the bonus of making an item useful). Btw, I don't want to 'nerf' casting or missiles at all, they wouldn't lose any power at all under my suggestions. I've already sort of started another RFE for that, though, :)
*one of the best things I've ever seen. gut goes to suicide on a GUV and finds a couple wishes. I manage to convince him to wish for the emperor moloch on the same level as the GUV; he exterminates all the greater molochs with ease. (later wishes for rings of the clear mind due to Wi stat drains). Unfortunately, he forgot about some of the lich summons...especially some little brown worms. they quickly started taking over and 700 brown worms later, poor ole gut was dead.
