Honor Set Bug

It's possible to enter the honor arena with mixed honor sets.
You can wear pieces from every single one of the four honor sets jumbled up and still enter the arena.
This is particularly annoying if you try to fight someone with the Lvl 100 Honor gear and your opponent thinks it would be fun to throw the Lvl 105 Honor Armor on.
The problem is that you get the set effect (blue sparkles) as long as all the 6 pieces of equipment are Honor themed.

Next update, the set effect only activates for matching level sets.
