First of all not that many people have t4 on fury (crom i heard is full of t4) and secondly not that many cheating to. sure it happens but not on regular basis.
And when this merge happens you guys will have much better latency and i see that as bigger issue than these you are complaining.
Btw i dont have any piece of t4 gear and never will because i dont raid, and still im managing killing t4 geared people in minis.
