I have one. (Ramar) I haven't used it for awhile, I was about 123 when I used it. I am 135 now...I might give it a look soon to see if it is usefull now. I has great power, for a shot. It needs good accuracy, especially for the special attack. (bring lots of $$! lol) When I was 201 ata, it missed online more than I would like. (offline it's easier to hit) I have 210 now....when you get about 215-220 ata it should own!
I differ with the racast thing....they aren't as accurate as ramars and won't hit until they are really high level, unless they wear God Arm. Besides, Shifta makes up for the power loss
Basically, it's a good gun if you are high level, but a liability if you are low level. It's slow rate of fire will get you hit often, so unless you are high level forget it. Also, at high level you won't miss much, and the power will be tremendous...I can see myself laying WASTE to huge packs of enemies in another 20 levels lol!
