Ok, someone of you guys may be really pissed about same look of T6/A3 armours, or honor epics and boe epics on some classes, for example paladin:
So to know what set enemy is vearing for sure, you just use model edit of T6 set into something different, so when you will see a paladin in opposite team, you will say for sure how many t6 pieces he wears.
Hope it helps you!
