Bounty runes mostly is a work for support players, who should not care about losing few creepwavesAnd for midlaner, of course, if he managed to push creepwave at ~45th second
I think more balanced with heroes but less freedom in gameplay.Before i can roam with slardar, all game stalk enemy jungle, pick timing bounty runes and come to lane to get 1 creep for full level. Now if you dont farm 10 creeps per second you have no gold and if you roam like that will be lvl 2 10 minute
SO, IF YOU WILL BE IN THIS STATE EVER, GO AND FIGHT IT, LOL
