I`m gonna come of sounding like a narrow minded douchbag now.
When I get into a lobby with someone using the BotB banner, I assume I have to carry extra weight that match. On ps3 atleast, the BotB is more then likely to score about 40k in a uug, and play their kit badly.
I have wiped, cos I got synced about half way throught w8 reaper gold, and had 2 BotB in the lobby that could not for the life of them finish the wave.
It seems like alot of ppl grind this banner for a long time, and see it as a free pass to drop into gold and plat and just ready up without any equipment on.
It brings a feeling of "talk the talk, walk the walk" to see that banner.
That been said, I have a few BotB encounters where they have been very solid players, but they are outnumbered badly by bad BotB users.
This is just my personal experience regarding the topic, and I may been very unlucky, repeatedly.......
