Hello,
I've encounter this bug with gunner, when you use reload and recall in quick sucession the cd on reaload isen't used yet you still get the full effect of reload making you able to use arcan barage/scattershot thrice in quick sucession. Unlike many other gunner's bug this one was fixed in apex patch. Is this an intentional buff for the gunner or is it a bug I shoulden't use in dg?
