This is the thing about classo, when you choose your four, it feels like your always leaving one good class out... we need 5!
Bring on Sloth IV!
And yes... to those who said using wraithform and necro pets on stab mobs doesn't work, that's true! I'd still rather have that class added to solo though.
Imagine getting all the way to thief 5x40... and what can you kill? All you can do is stab mobs... and can't kill any of those nice big eq mobs with the candy. Just seems a waste to me, to have a 5x40 that can't kill anything big... unless you have your eq sets already or sorted. I've run with a few avatar thieves. My survival factor is higher at 4x40 than there's is at 5x40. Seems a big sacrifice to have it that way.
But I guess if your playing thief to start with, you'd already understand this was going to be the case... so mute point really. Thieves are about quick fast xp, casters are big solo's/slow starters, just the way it is.
PS Spectral is way overrated when you have low hp, high mr regen, and your not running desert or in a group. Because I have low hp regen, any mana regained by spectral is often spent on casting heal to keep me alive... Shifted, it's a better. Darksight rocks!
