As to HP, I've always felt the more HP (or other mitigation) I can get, the better...as long as it's not a detriment to the rest of my character. I agree that people who say HP isnt'a big deal are wrong, but they're not COMPLETELY wrong...HP is important, but it's not most important. As I currently have the cleric dilly on my Paladin, I'm currently considering an LR +3 to change the 2 fighter for 1 fighter 1 artificer (gaining me full UMD and a couple other minor things at no appreciable cost), just to pick up displacement scrolls primarily to supplement my defenses. Then again, the most fun is had when things very nearly go wrong (and in EE soloing, especially as a melee, you're one mis-click away from dying pretty often).
I'm keeping an eye on the enhancement system for my sorc, actually. I'm rather tired of the shiradi build, and looking for a way to make DI work for me again without costing me many resources to keep from re-entering. Not planning for much, though, because I'm hopeful that what we see now will change a LOT before it hits live. Once I know what we're working with for enhancements, though, I'm intending to change Wruntjunior over to DI caster...and my monkcher will likely change out of necessity.
Also, 2 new videos are in the process of being uploaded...one of my sorc doing rusted blades, one of my paladin doing Trial by Fury (though it got cut short due to FRAPS malfunction).
