I'm still trying to figure out what my favorite blaster is.
The DL-44 is a gun I always end up bouncing in and out of, it's basically a space deagle. Useful for medium range assaults mostly, you can snipe a bit with it if you have the steadiest hand, it's the only gun I find my self mainly going for headshots with.
As I am sure is the case with most people the RT-97C is my go to gun, it has decent damage, incredible range and it's just generally really reliable, the one thing I dislike about it is it feels really clumsy at close quarters, to the point that I can't really hit anything in there.
The DH-17 is the blaster I underrated the most, it's one of the first things you unlock and it's like 600 credits so I figured it was there to introduce players to blaster pistols but this gun is seriously a really good workhorse. It's absolutely awesome in close quarters, rather solid at range and it's got the perfect fire rate where it is always really easy to control. I feel the DH-17 doesn't get enough credit.
The T-21 and the T-21b kinda feel like long ranged versions of the DL-44, they're cool but they're not really what I want, I'm not the most accurate guy either so between the slow fire rate and the fact that it over heats quickly I can't really use these very well as I can't really correct my fire mid spam.
I oddly enough haven't given the E-11 and the AC280 much of a go around, I should since people seem to love the E-11. I just picked up the EE-3, it's got similar issues as the SE-14C where unless you hit the full burst it doesn't do much work, but if you hit the full burst it's completely devastating. Since I don't have the steadiest shot they're not really guns for me.
The jawa gun the CA-83 or whatever is a gun I only find myself using when I play blast, in blast it's really really strong since the maps are really close quarters because outside of that that thing is useless to me.
All in all though I'm really pleased with the weapon selection, they've all got their niche. The only real overlap is that the DLT-19 and the RT-97C feel a bit too similar and considering the RT is just flat out stronger stats wise that's a bit disappointing.
