I'm seeing lot's of good advice in this thread but, OP, you're not alone. I've been making my way through but I've been finding it very daunting and the level of micromanaging required to win kind of drains the fun for me. (I still love the game, just not in love with the current gameplay balance.) I've been finding success with using a lot of crowd control and trying to position larger fights in a choke point or places where I can get the higher ground. To be fair, I'm also running with an awful party composition because I dislike the tank and healer we have with EA.
