so Aresas, bluechees frosti and my alt were getting broken shields whenever we joined an arena level. the shields were permanently broken like the ones in the advanced training hall. there was no explaination, but we think it may have been caused by joining Aresas alt account to farm the arena. was this on purpose to stop farming? or is it just bugged?
Same thing happened to me when I joined a party at the last party button room in Smoldering Steps. No alts were involved, though.
