Mostly what should have been done is stop making grand company fights, and should have seen this coming. Also measure should have been taken with how we have linkshell, and cross-world linkshell. Then again should have made another rival wing 2 teams pvp, and should have fully test BH or made adjustment to it first. And another thing SE should not under estimated the player, players will find bugs or exploit in the game they can abuse to gain an unfair advantage that doesn't break the ToS. Also another thing all range dps is at a disadvantage in or currently how powerful melee can just power through and kill 1 range dps(give or take if that range dps is good) with a healer combo at 0 BH.
