And why some weapons/parts have always performed better than others is a marketing strategy to make money.
Create a competative pvp game, give everyone many weapons/parts to choose from but make 10% of them slightly better than others.
Ignore the cries from community about those weapons/parts being imba.
People will come to believe after awhile they have to use/buy the weapons/parts that everyone says are imba to be better than everyone else.
Result:
People spending money on a free to play game to get the imba weapons/parts and dollar signs in Targem’s Bank account.
