Wu Kong, what do you think of him?

I agree see Note 1.

Lucky it is relatively easily to get a 4* yellow hero since there are only five 4* yellow. Unlike HotM which can be difficult to get or impossible if you just joined the game.

However, Wu Kong is OP. So just like the popular Ramming Pulverizer, there should be a purple Gambler’s Stance and a third color Gambler’s Stance. This would make Gambler’s Stance similar to 42% healing, a major 4* special skill.

Personally I think the red 4* Heroes ( heavy on aggression) would work with Gambler’s Stance. So yellow, purple ( strong against yellow) and red Gambler’s Stance.
