He already won an S tier aoe4 tournament.Being pro:
Hera's only chance at being a pro is in AoE2 because he has so much experience in that game. AoE4 will take too much grind to get to that same level and same with LOL except that the competition in LOL is 1000 x more intense. There are so many players in LOL.
He can definitely be a top4 (or at least top8) aoe4 player if he's really interested in the game. Seems like he doesn't have the motivation for aoe4 anymore.
