What do you mean OP heroes are okay if they’re “rare”?? If you support that statement, you are the whole reason why this game keeps having ridiculous power jump that will eventually kill the game!
Don’t you realize that the game has gotten horribly P2W FOCUS now?? Look at the previous HotM for the past 2years++ where you get GM, Hel, Kunchen, Frida, Athena, Evelyn, Kingston and all of them was super strong for the time and guess what? The game was more balance in term of f2p and c2p getting decent heroes to compete because they are more likely to get HoTM and it’s better for larger pool of players. However look at where we’re going now?! Ninjas are OP and 100% P2W only, bunch of heroes on s3 are OP and again, definitely favour P2W. Above all, when you think it all ends, SG just need to release even more OP heroes on S4 or new events for again P2W (which increased the gap for F2P/C2P players even more to be an "underdog"and probably the end to those players once they can’t do much anymore).
However in the end, even P2W will never win because SG can keep releasing even more OP heroes than what they currently have. You’ll have to spend so much money to keep up with the trend of SG which basically just code the new special of heroes which is not very hard at all.
This is why, there shouldn’t be any heroes that’s beyond super strong and can’t be countered, otherwise this “rarity” soon will never be rare anymore by the pace of SG releasing OP heroes one after another.
