it should be noted that its talking about 5/5 keg, it wont burn now, it will just slow, does that mean only 5/5 FF will be the only part that heals? there will also be cooldowns for being given a gunners shield, but what if gunner 1 gets gunner 2's shield, but then gunner 1 wants his own? il watch the pte guys reactions
edit: apparently from forums, the new FF gives 8% of total health every 4th shot, thats 12hp for 4 hits. 10 seconds to heal 72 hp.
