Something is wrong with Jingle Hunter AI in arena. It was so strange despite how easily my team decimates enemy teams i keep losing a lot of defense fights, so i tried couple of combats in Auto-mode to see whats going on and OMG..

My set up is Bloodpainter fills meter>>>> Warmaiden AoE+deff debuff >>> Jinglehunter base attack????? and noone was even close to die  or anything.. makes no sense.
sometimes he uses Ice arrow instead of AoE nuke even being 4 enemies alive, thats not good but acceptable sometimes. but Just the basic attack on first turn when all his skills are up. That's not acceptable.

Imagine if u are in the arena, the enemy takes the first turn, and kael just do a basic attack instead of his AoE! that would be ridiculous... 
I'm a bit disapoointed with this as i built all the team arround jinglehunter.
