STOP RIGHT THERE ........this will hurt everyone not just the MB :
-Any Ganker Solo-hunting for returning Mavericks at Towers encountering somebody who he cant just Alphakill sooner or later , Fight drags on , somebody of his own faction sees and wants to help...suddenly he become perkable ...reclaim ...WTF .
-Somebody who is feared running into Teammates ..... WTF
-Roughly 10-25 % (my feeling , cannot back that up with hard Data ) of the Highlevel Players own a old Toon from Times before they changed Faction or even have a purposebuild Toon of the Opposite Faction to leech Tarasque no matter what Faction currently wins in Camelot ... how long do you think it will take before somebody "accidently lags " or outright Airdrops with the malicious Intent of killing somebodys Offense&Defense.. even worse somebody doign that with a MB debuffs you even more than a Single Toon .... dont tell me that wont happen , if (insert Swearword) are desperate enough for Winning all the Time to make 2-3-4 different 6Box and even 12 Box i suspect they will do ANYTHING short of Murder just to win.
-Speaking of Camelot ...even the smallest AoE-debuffing Aura is too much in such confined Space ,pretty much the same goes for Will to Fight if that place becomes popular again.
-There are some pretty tiny Towerfields ( few in Highlevel but more in TL4-5 and below ) where such a Aura would be potentially harmfull.
-Wakizaka is right this makes Mass-PvP even worse for Melee than it allready is
-How about Neutrals ? They can be on both Sides of the Battle , who do they debuff and by whom do they get debuffed or not
Im about the last Person to defend Multiboxes but this is the wrong Approach , too much collateral by Accident and too much potential for Griefplay.
PS:
No i dont have final Solutions either , my idea with the randomized Tab might work or not , depends if the MB rely on Tab or are really using Targeting Scripts allready...
