this is about whether the unit actually tips battles unfairly and even a high ranking player can't beat it.
There is no such unit that makes it possible to beat a high-raanking player if you ae considerably worse than him at the game.
Not a bad idea, BUUUUT even with the OP stuff, very few players can beat the top players. Even if you made them more OP, they'd find it hard.
How about the same idea but matching the players against another player of similar skill?
Remember, the OP things only tip the balance a little. There's nothing in the game now which is an auto-win button. Mostly they just tip the balance 3-5%. (Or just make the game incredibly unfun to play, Maxim VonMaxim)
You'd need more than 3-5% to beat Jesulin, Barton, Cruzz, etc. Everyone would lose to the pr0s, so with your method, nothing would ever be OP. I say bring back the old Pgrens and Flamer HT then put this method in action!
