Spawning at a sundy cost infantry res?

[Chewy]

What if it took 5 infantry res to spawn at any non-static spawn point? (AMS)

During the entire beta Id never touch infantry res till I ran out of grenades or wanted a MAX. 80+% of the time I was sitting at max infantry res because there's was just nothing to spend it on. I don't even know what it's used for outside of the med tools (I main medic/engie so useless), grenades/C4/mines, and MAXes. It seems like a waste to me for it to sit unused.

If it cost 5 res to spawn at a sundy or drop pod (maybe up it a bit for pods by adding 5 mechanical) then attacks could, in idea, be halted by a good defense if not flat out stopped all together. Forcing attackers to fall back and save up for the next assault while giving them a chance at defending for a few hours.

It could also make defending a base worth the time to do so. Seeing how defenders get free spawns they can have a chance to push attackers out of a base or to their last outpost.

This was just an idea I had 20 minutes ago and clearly not very thought out. So feel free to rip it apart and give you own ideas on it.
