Lol'd.
If the current leveling experience taught players how to be good at the game, we wouldn't have about 90% people unable to handle anything above LFR in the game. The leveling experience was piss easy when I first started. My interest in getting better = what made me a good player. The same goes for everyone else. You even have people fail at the most basic-ass rotations in Classic ffs.
You're making a hen out of a feather, a feather that doesn't even exist to begin with.
