Trials is the same boring routine! Use yor sniper as a primary weapon as there's plenty of ammo and aim assit does the work for you. Camp, hardscope and walk around corners whilst looking down the sniper scope. Once one enemy team mate goes down, have one guy camp with sniper for revive whilst the rest move up with snipers out. I think a good solution to making the game fun and fast paced is to replace the heavy round with a special ammo round in the third. Also stop allowing weapon ammo regeneration perks to give ammo to others if you swap snipers quickly! I think this will make primary weapons your primary use and not sniper first! This to me is a more fun and challenging solution!
