In the latest developer interview, Overwatch's game director (and former WoW game director) Jeff Kaplan has shed light into the new class balance philosophy that the team has adapted:
"We're also going to change our balance philosophy, which is going to be: balance more frequently, more aggressively and be less concerned with trying something and maybe pulling it back later... we are going to try some pretty aggressive balance changes. We are going to deliberately target the meta. Before we used to balance with stability in mind, stability of the entire game, all players in mind. Now we are going to balance more aggressively targeting the meta and moving you off the meta as frequently as possible"
Do you think that Ion Hazzikostas and the WoW team should follow suit? Classes in WoW are often left untouched for an entire raid tier, and it is always the usual suspects who are at the bottom of the barrel in DPS (Enhance/Elemental/Windwalker, Arms, Arcane, Unholy), Healing (Mistweaver, Holy, Resto Shaman) and Tanking (DH, Warrior). It is absolutely not fair to all these specs in the game and the players who would like to play. The meta at the top undeniably trickles down to the rest of the playerbase.
