Don't bother getting Yoda. (A disappointment in high end Arena)

I am first in arena with him .
Top 200 in my server are all 27k+ power .
Arena is randoml , everyone Can be first or 50 with same opponents And teams.
Defense is random And computer don't play as human. Ai is not good for that but not only for yoda, for all.
But true Ai is sometimes better for some chars than others , but it's a computer not human
