Ok, the title is a little dramatic but I need
to get your attention, Plarium. 

I've dug through old posts on the forum and issues similar to the one I'm bringing up have been brought to you before. You're fresh out of excuses. 

Champion AI seriously needs to be addressed. My specific examples are as follows; 

Royal Huntsman won't use his A3 (the very skill that warrants his status as a legendary, mind you) against the CB or dungeon bosses. 

Spider won't use his A3 against the CB. It's a defense down/weaken ability, why on Earth would he hold that back?!

Kael won't use his A2 (his highest damage-dealing attack) against the CB or against dungeon bosses once all minions have been taken out. 

There have been many posts on here about broken AI yet I've seen very few fixes in your changelog. 

I don't mean to sound like "one of those guys" but I'll have to withhold any further financial investment into this game until major issues like this are addressed and I'll encourage others to do the same. 

Put yourselves,  the player's shoes; would you knowingly purchase a broken product, especially if the supplier has demonstrated no intent on fixing said product?
