You would have to increase the level and strength of the guards of neutral cities like Gadgetzan since a high level well equipped in those areas is unstoppable and damages the gaming experiences especially when it is shot killing you a whole day without stopping
Warmane is an ecosystem, lowbies get killed, the strong ones push through. Each leveling zone is a new guantlet, each time the herd is culled. Until finally, you make your last dash through storm peaks, where the final trials of K3 are endured. And finally, should you survive the numerous ganks there and finally reach 80, you can become the full grown toon you were meant to be. What doesn't kill you makes you stronger my man.
