I see what you did there. It's a tool for wings, really. A gun that replenishes the shield of wing members and won't even do damage if their shields are down. I see you base this of some sort of hidden value (shield frequency?) which you share with your wing but no one outside is supposed to know. That's some Star Trek level handwavium so I can live with that.
But wings already have the advantage in any combat situation anyway compared to a lone ship. Also, the new tool allows wings to drastically shorten downtime between fights due to slow shield regeneration. What is a lone player to do in that situation? Are we going to see an equivalent to this, a device that is activated like a weapon, consumes WEP power and replenishes our own shields? Or is this your (FD, collectively) way of "nerfing solo" indirectly by adding extremely useful tools for regeneration and downtime reduction unavailable to solo players?
