It's like that in many games
old game like neverwinter, there you will in pvp often get matched against ppl with much higer item levels so you want to improve your own gear using microtransactions.
The same in World of Tanks and World of Warships.
Plenty of players to make matches all in same tier, but noooo, lets put +2 tier player in the mix, so ppl want to buy premium to get faster XP and that way get to higher tiers fast. And but so your captain/crew is improved. And so on and so on. Now I'm so sick of it, that I will simply exit battle whenever that happens...
This is a crappy trend that is spreading like a disease in many many games. Games wich I will support no longer. Hope more will do the same so we can get back to games that will be more fun to play, and where it's not pay to win...
