I only played as the soldier / assault class so I can't really speak to the other characters. (metacritic.com)
While using assault class, always keep in mind that the weapons are not long range. (thetech52.com)
A last - man - standing snipers match with no respawns was more fun to spectate than it was to play (for most players anyway), while a head - on assault that has two opposing teams of assault class soldiers trying to take a line of five capture points in sequence quickly bogs down in stalemate.
