Sorry I'm late folks. But I'd love to see some more things for COR.
Mainly:
1) Single Target JA for rolls
2) Movement speed and/or haste roll. One of these can easily replace BRD roll.
3) More QD options or abilities/traits, whatever.
4) More level 75 gun options, especially hexaguns. It's kinda sad when our main options are Martial, Murderer, Coffinmaker and Corsair's gun only. All of which are high delay shooters. More lvl 75 Hexaguns (ie: low delay) other than Death Peanlty would be nice.
Giving due credit to Aledacia for some nifty ideas I liked.
