I guess the Dev's did and do look at all this we put but I think with the game crashes and vehicle lag they have more important issues than abit of game balancing at the moment.
I just think SBH's should be a class that you need to know how to use properly and that it does actually need some skill to play, as at the moment anyone can grab one, run to enemy base and plant nukes/Timed C4.
As for people moaning if changes are made to SBH's, all I can say to them is just learn to play them with abit more finesse
