I think stacking is a non issue, unless leagues want to ban stacks of more than 2 - thats their business. {Carcifier} The map makers knew about stacking and straffing, im sure the beta testers tried all these things out. Bank vaults missing texture/shader and maps where you can go landsharking are map flaws more than bugs, and dont radically affect map balance.
the tap out bug is another Ive been wondering about. I think making it easy to gib the fallen is intentional. There may also be situations where a player is gibbed when not being fired on - the tap out bug. these mystery tap outs may also be intentional - SD never commented on it, we can only assume.
end of game stats bugs really dont affect gameplay, so I consider them minor. actions to whore XP or actions that result in no XP only suck for the XP minded : ) the hit box issues, as per another thread, arent really bugs, just a reality of server side bandwidth we’ll have to live w/ for now.
