It's fun, but not actually very practical, since the AoE takes forever, and it has short range. But it is a decent weapon for a BO.
It was very practical for my BO's (and me) who can stun/immobilize/hold enemies and close the gap to use the special attack.
The only downside that I noticed to using the AoE is the aggro it gained me if I was using the weapon directly... perhaps it's a bug, or a feature, but it seems that my Sci BO wields it with more safety than I do.
Don't use it if you heavy geared VA1 but at lover it kicks but. It has a stacking cold effect and with 1 sec cool down it is a nasty weapon. I have had so many stacks on a mob they just stop in there tracks.
I actually equip it on myself... I give all my BO's split beam rifles (All humans with the 'teamwork' ability) and I have the CRM200... What a combo! Seriously, I use the AoE setting... next thing you know at least half the mob is vaporized seconds later. GAWD what a cool ground weapon!
I support anything that helps take down mobs quicker. It seems to me like there should be one or two really weak guys in a mob. Just to give you the illusion that you're using "weapons" to fight. Sometimes I spend a few minutes shooting guys in the chest over and over with my phaser and they just keep doing the same to me. I thing ground combat just takes too long, but this type of weapon certainly helps.
