agree with dantoo - manned 5" are already essentially just for griefing, add them to bases and you'll extend that griefing to land as well as sea. if you want to defend a base, up from the next one over in a fighter, bomb the enemies field, or if you've completely given up on trying the challenging stuff up a wirble.
the ridiculously overmodelled puffy falls under the same category as weapon jams and random engine failure - does nothing to improve combat, just causes irritation. if I get killed by another aircraft or gv I can learn from it and improve my chances next time. the only lesson from being killed by the current puffy is: dont go within 10 miles of puffy.
I'll also add that proxy-fused puffy has no place in EW, MW or most of the scenarios and special events. I guarantee that realistically modelled time-fused puffy, properly modelled would never be manned.
its the one aspect of this game which really annoys me from a gameplay POV, its like adding AIM9s to our current setup in the sense that the modelled acquisition and tracking is tech from the 50s/60s at the very earliest, and has no place in a WWII game/sim.
btw if it was modelled correctly I'd actually like to see alot more ack.
