The DPS is pretty good, and the cooldowns almost align (4 and 3.87 due to quirks), if you get cooldown skills they diverge a bit more. UAC20 as Tank mentioned in another thread is also an interesting possibility, but i'm wary of the heat.
I would think Cooldown skills would bring the cooldown a bit closer together, since it's percentage based. For example, dropping 5% off of each brings you to 3.8 and 3.68. Of course, at those levels, I doubt you'd notice the .01 second difference. ;}
Actually, the base cooldown of MRM30s is 4.3 sec. You have to solve 4(1-x) = 4.3(0.9-x) where x is the amount of cooldown reduction you get because everything scales linearly. at x=0, the cooldowns are 4 and 4.3*0.9=3.87 respectively.
4/5, I downgraded... well, everything to fit a LFE 325 since Im simply not comfortable with an XL Victor anymore these days.
5/5, I recently got back to MWO again and decided to build my victor up; I'm loving both this and the srm6s variant. There's an engine sale now so I made mine with LFE300. _ VTR-9S ::EDIT:: Woops I linked wrongly earlier.
I switch mine to a LE300 sometimes as well, XL340 mostly when I have it lying around and other mechs needs the LE300 more
