I have 5 primaries above 300 (1 is 310) I have 7 secondaries above 300 (2 at 309) I have 6 heavies above 300 (2 at 310) I only use raid gauntlets, so the rest of my gear has been infused up to 310 (besides cloak and boots 😠) on my hunter. Then my warlock also have infused gear up to 306 light. BUT, I think the biggest thing is that I play a LOT. I have 28 days played on my hunter alone. And do a lot of court of oryx and get really lucky with engram drops. I usually dismantle anywhere between 20-30 legendary engram every week.
