The better optics and move faster while aiming down sights

Well, it's your call overall, but all those middle perks aren't really that good in this case. Zen moment and firefly are arguably the two best perks in their respective positions on ghelon's demise. You have to decide if you want to risk your two good perks for a center group that has something like AP rounds, explosive rounds, high caliber rounds, or flared magwell.

I really like my roll I'm prolly going to keep it it's done me good, another person mentioned explosive rounds is sometimes buggy I'll prolly play more ib in hopes of finding another GD so I can reroll to my hearts content
