hm, yeah theres a slight shortage of tanks around late 50's early 60's too. i imagine tanks are in even shorter supply on pvp servers. thay have retarded survivability (guardians and dt's) but not much damage. Except guardians. Guardians seem ridiculous good.
just hit 60 last night. it's mostly grinding now, with 1 or two quests here and there. I haven't been to atzels yet so theres probably 2 or 3 more there. They've got a big content update coming for mid-end levels sometime in june if you didn't catch the dev notes. Might level my alt untill then, dunno. The lev 60 destiny quest was pretty awesome. I liked it.
