I'm pretty sure <2 seconds TTK, is not very ammo draining. In most situations, it's easier to die, than to run fully out of ammo. Specially out of ammo twice with the ammo pack. And even less likely , like my ork shootah, with big shootah and double pack. People camping, is just a consequence of this low as shit ranged TTK. It was buffed so hard, that even ranged is afraid of going outside against other ranged. Ammo in this game is not an issue, unless every second you spend moving from point to point, you are shooting at the sky emptying clips :\
If I'm not mistaken we already have health regen to a certain degree: 1. Armour 2. If you are badly wounded your health will regenerate to 1/4 after a few seconds (or was that removed?) regarding ammo: pls no ammo regen... we don't need it. every regeneration feature makes the game less tactical and more casual. Even though "regeneration" on some supply items is fair enough (health nades, maybe ammo supply boxes). Maybe a 1/3 or 1/4 ammo resupply on an execution would be fun... but besides that: no, thanks
seriously? the unlimited ammo is one of my biggest NOPES for overwatch. there are already enough supply boxes at every point to restore ammo and health. you can take ammo packs or health packs as items. healers healing you. Although I would like to see an support item that places an ammo supply box where your allies can regain some ammo.
If you need to talk about ammo and resupplying then talk it here. http://forum.eternalcrusade.com/threads/ammo-shortage-ahead.64776/ The poll is up for quite long time.
There are various ways to replenish your ammo. You can do it yourself, twice if you spend the LP, or you can ask for it from a kind support player, or you can run the short distance to a supply chest or transport, which I am sure you would be near if you were playing tactically anyway.
