The main two problems with these two brackets is that
A) Level 50 players with Relic +1 weaps or even Zenith weapons are queueing in these brackets. Even with level sync, they are so overpowered that it unbalances the playing field.
B) Said players above are often queueing with FC mates to form premades of mixed 50s and fairly well coordinated non 50s. Result is faceroll against other team. Extremely unbalanced.
First of all, 50s should not be allowed to queue in level 30 or level 40 pvp. I don't know who's great idea it was, and on paper the idea of playing pvp with any of your friends sounds good, but realistically, it does NOT work out.
