I played my enc a little bit this last week, solo only. Yeah, they really are squishy. In my experience only patience helps there, sticking to blue/light blue mobs and fully healing between each fight. Reaching lvl 6 really helps a lot (Illusory Weakness is just as great as I remembered it). Lvl 5 Runeskin should help, but tbh it feels like it isn't working. I played a cleric this time too so I'm definitely spoiled by the barrier's awesomeness. But the Runeskin effect should still absorb 50% of damage...and it just doesn't feel like it. No message in the chat for absorption either. So, I'm not sure if it's really working or broken (didn't check the bug section in discord)?
I disagree about the casters getting the same spells at low levels. IMO it's part of the fun as a lowbie wizard to start blasting right away. Wouldn't want to take that away from them by giving similar nukes to the other casters as well.
I agree that the suckage on early Ench needs to be toned down a bit. Some class has to be the worst early leveler, and it's ok if that's enchanter. But whoof, it's so miserable. They should get the mana regen buff at, like, 6, to have an exciting group contribution. And the first mes should better than it is, IMO.
