I'm finishing up as a CAST AT and its a little awkward. I have no problems doing support but I like to get into the fray more since my MST is useless. That way too I can get my SUV up pretty fast with the increased attack speed and some crazy whip action; LKK and buffs help big time.

The only time I'm forced to play support-only is purely technical. Between my connection/ping speed and occasional chugging I'll have a hard time tagging enemies in a fast moving group, so I hit the debuffs as quickly as I can crank em out with Har/Quick.

I DO think there should be job system where if you get to lvl20 AT you can pass S rank whips to another class. Just a final fantasy anyway XD
