I know what you mean by the skills, but do you have any +healing abilities stuff on your items? I put some of that on, and it increased my healing loads! I use blood healing too.
The abilities show their base damage, which doesn't include any modifiers, I think its meant to be like guild wars and to an extent diablo 3. Where the top end abilities aren't neccesarily the strongest, but can be more useful. Although the elite skills do seem to pack a mighty punch.
I'm enjoying the game mostly for the storyline and the world, its a given in MMO's that you'll have to grind, but the story arc in this game is well thought out and pretty epic.
I'm going to give a few months chance to sort itself out, theres promise of monthly content updates and what not, so I'll see if they live up to their promises. I'm not expecting a 100% perfect game, especially with MMO's, and I've read far too many reviews of people saying "it doesn't do this/this/this/this as well as WoW". If you're undecided, I'd say give it a couple of months and then check it out.
