No they're not. There are racials in WoW. If you can increase your dps by 0.2% by paying 80$ to switch to an otherwise inaccessible race on the wow store, that's p2w. As long as everyone can achieve that power without paying a cent other than subscription fee, it's fine. Same thing goes for buying gear that isn't accessible from things like timeless isle or other catch-up mechanics. What's the point of character progression at max level if you haven't earned it? That just defeats the whole point of an mmo.
