I have to ask - has this actually been a problem in a real combat situation to date?
Are there wings flying around with healing beams circle-healing each other that y'all just can't destroy?
If the answer is no - then this video may have just created such things, and you've pretty much said "Hey everyone, here's our weakness."
Could it be that you've just been outwitted and don't want to admit it?
I don't expect an answer to this - it's hard to admit defeat some times.
As a non PVP player, I am not without sympathy to issues that affect other areas of play, including PvP. However, this sort of activity does not do much to win any sympathy to any given cause, and I have to fall back on my original question: Are there active player wings employing this tactic that you simply are unable to defeat because of it?
Personally, I'm in favor of leaving this alone, if for no other reason, it gives players a reason to use this sort of weapons modification to thwart PvP attacks - especially those they would call "unprovoked."
And I will end with one more question:
Would you rather people simply combat-logged on you, or called in an unbeatable healing circle?
