I am sure that i will pick up more, later tonight during the guild event, but my experience in the Beta area has been lackluster, at best. HoT seems too much like dry top, with elements of the SW added in. The mobs seem to be more of the "let's add more health" type, and not all that interesting. I know that much of this comes from me not understanding most of the mechanics, and that is part of my problem, but I found that I was so disinterested that I didn't really care about the mechanics.
I find dagger Necro more fun than the great sword, the GS hit too slow, feels like playing in molasses. Guardian bow is nice and functional, but I found myself using GS mostly. I will try some of the other classes, but I really don't like their gear delivery system. I bet I spent 15 minutes, x2, clicking through inventory. Give me a darn vendor already, so that I don't have to spend so much time clearing up my inventory!
In my limited experience to this point, I give the HoT beta a solid ....meh
I am generally not a complainer, and I always do my best to find the positive where I can. Even after sleeping on it a night, I find myself wondering why i spent any money on this expansion. I hope that others can help me find a silver lining, somewhere.
