defensive ammo? (in General)

the + is way too cheap or am i the only one to think so?
since people are calling out for an evasion/TOA nerf shouldnt defensive ammo be nerfed too? i hope jon reads this and deletes upgrading of ammo or something -.-

The cost of a plus is hard to set for ammo, since you pay for the upgrade on each missile in the stack.

Here's an idea... pay money to "brand" ammo onto your weapon. The two items then are always equipped together. Like, you equip the bow, and the arrows go with it. The arrows are treated as normal -- you buy more and merge them in. But to switch from giant massive ammo to normal ammo would require rebranding to a different stack.

This would also eliminate Merging branded ammo down to base after its been upgraded, to prevent the obvious way around it.
