My 0.02 inf...
I played ELM/ELA for a couple of hours last night. Objectively, my performance was typically Brutish. I cruised through missions. I ate up even level opponents like candy. I survived fights that would have been death for any other AT.
SMASH! and all that.
I just didn't
feel very brutish

I believe the reason is the zappy sound effects of the attacks. With all the other Brute primaries, your attacks sound like you're dealing out the punishment. Which is fitting since its a melee AT. Stalker attacks have the same sound quality. Ninja Blade
sounds like you just sliced a chunk out of something.
At the end of a big fight with me and the other ELM I was teamed with, there were 15 bodies laying around on the ground. Clearly we had performed our work with Brutish effeciency. But I just wasn't left with the feeling of "Boy, we whacked the crap out of those mobs!"
I agree that the choice of the SS animations wasn't the best. If I am going to do a 2 handed overhead smash on someone's skull, it should sound better than "bzzzzip". Even the powerpool Air Supperiority attack (same animation) has a respectable twack sound. If they are going to keep the same tepid sounds, the Fire/Scorch animation would be a better choice. Its more of a "reach out and touch" attack than a smashing move.
Comon devs! We're going to be hearing these same attack sound effects for 50 levels. Make them impressive! Or at least respectable...
