No it is not P2W i do agree with that, the definition, like it or not, i do also think it is the one that @
Asmodias gave.
This boosting thing is the consecuence of the F2P strange model that wow uses.
To encourage people to buy tokens with real money so they can support the sub of the ones (me included) that pay the sub with gold, they are turning a blind eye with this boosting practices that go against the design of the game itself.
The idea of the game clearly is not that someone gets decked with heroic or mythic gear by buying it with gold or with real money.
Also they need to bribe raiders to provide these services by letting them profit and playing the game for free.
I get why they are allowing it, but i do not like it at all, and although maybe it is necessary at the moment for the game to keep running, i think it is gonna be real bad in the long run.
