I didnt pay boosters ever and have better gear/progress/performance than you.
I said it many times and will do it again: GEAR IS THE LEAST FACTOR OF YOUR PERFORMANCE IN PVE OR PVP.
Shitty player pay, shitty players get gear and shitty players still have worst performance. How is it pay 2 win if they cannot win even with better gear?
Pay 2 win is when you pay money and DESTROY other non-paying players (by dps or in pvp etc). When you pay for boost and still do shitty dps after that even with gear - its not p2w.
Besides, buyers can easily be detected in raids/parties - they have good gear, but shitty dps/hps.
