Heh so I was int-bird since lv 1, and I can tell you they are not weak. Currently I am hybrid int/dex-bird, with armor of 137 and dps of 204 in combo with 36 crit. This is good enough to tank all stronghold rooms, as long as your h/s is 25. Many builds are possible, cause no sets exsist. A glow stick with 48 crit guarantees you all attention from any boss. No RR, FF or MM can get the attention (taunt like?) back once you start. So if you want an aggresive character going in first and killing bosses, be sute to join us (rare) int-birds.

I'm still tuning for pvp. This week I pvp-ed for the first time so I need some more experience. Right now my conclusion is that Str-based opponents are easily beatable. Custom RR is 40-60%. MM is still problem though.
