You might have to wait a few days for informed opinions (game released proper on Monday) but i'd agree with what you saying. Bazookas and sniper rifles would sully the experience, are you able to respawn on that map? cause in that case I would say allow rockets and sniper rifles cause in a last team standing type game the odds would be to heavily stacked in the axis favour.
