Cycler is much better than the pulsar and moderately better than the gauss...thats from what I see and experience.
I pick up a cycler and notice suddenly the entire game gets easier, its a weapon with minimal recoil, very fast firing rate, and deals outstanding dmg at close range, long range it only does armor damage (maybe a little hp damage), but with a 50 bullet clip, you've got more than enough bullets to take down that enemy.
This is where the gauss beats the cycler, the gauss hurts at long range. But the gauss shoots much slower, with a bit less accuracy, and then theres the pulsar which I just call the vanu crappy weapon. (I think of it (pulsar) as a gauss that doesnt pierce armor at long range.)
Anyhowww... I think the cycler needs tweaking, such as a dmg tweak, or a clip size tweak.
I'd also add a little thing about the sweeper shotgun, it does the same dmg as a jackhammer (give or take a few hps) but has 10 less rounds in the clip, I'm not so sure its balancing as it only takes 2 points to get.
Just another thread about the opinion of balance within game.
What are your opinions?
