Reload speed isn't really nerfed from previous games, the perk just makes it much faster. As for the grenades, I wouldn't say making them all more powerful across the board is a good idea. Not sure off the top of my head though if you can stack the grenade pickup mod with the reduced flinch.Even Forged versions will suffer from some of the limitations that the sandbox design of Halo 4. No matter if you don't have AAs, you still have to worry about which 2 aspects you are going to bandaid up. Weapon reload speed, grenade pickup, explosive damage, etc.
