I don't know if you've been listening to what KD said but there's a good reason why the weapons aren't carbon-copied from the 2D games and they're not going to change it to--
the megabuster is a bit too strong
but yeah, in a nutshell your suggestions are only going to make games, especially Deathmatches and the like, drag on for an eternity. People have to die at some point. Lowering damage
and increasing armor is a really, really bad idea. You'd be lucky to even
do 5 damage with most weapons! And when people generally have 100 HP, and health and E-tanks are almost always available in non LMS games, people will essentially be living forever. There will almost never be any other conclusion to a battle than people getting bored and quitting.
