@AbsoluteZero the sniper rifles and pistols wouldn't work especially not the most OP sniper steampunk (especially considering the random crit chance would make them super inconsistent in bbg and over time people would start to hate them).. I don't think most of the weapon types in BBO would work in BBG maybe futuristic ASR but i haven't played in a while so i may be forgetting something.
The armour sets could be made into skins as well *cough* graham shark *cough*
Saberi's unpopularity comes from the fact she has no class role when you buy every other class you expect something but saberi no one knows what "combat tech" means.
Balance in BBG is a pretty high priority considering a ton of OP weapons and and even larger list of UP.
Everything else i agree with but maybe the BBU candyland spawn camping would need a touch up on (maybe having different spawn rooms?) if they used that version of it (if they do put it in BBG). I think a map that would worl really well in BBG would be that dark island map with the springs ateach side bringing you to the middle.
