Ya sniper is a great class with several uses. Being a major burst class it is gear dependent in mm spec and yes you probably can help your team more in many situations in an eng spec (and you can get higher chart numbers while doing it lol
). If you like MM then as you gear up just keep trying it. If you can afford augments then by the time you have full bm with maybe 1 or 2 wh pieces you can switch back to MM and burst most people down fast again.
