Hi just an idea that's stems back from rpg games of the past. The idea is that if you equip multiple items of the same armour set/tier you get an additional bonus. Maybe something like an extra 5% bonus If you have 8 items of the same set 10% for 10 and if you manage to get and equip all 12 you get a 20% bonus on the stats the equipment gives you. It would encourage players and clans to do all the EB's to get the full sets.
There's a problem with this to do with fairness & balance. Everyone can get the eb equips but what about the rancor set or future limited edition equips? The rancor equips are the most powerful in the game but only a select few will have the complete set. So not only will these players have the strongest equips, with this idea, they will have a further 20% of those powerful stats on top of what they have making them unfairly powerful.
