So i went too a Bg, busy atm, all i could do was one, i turned the interupt setting too 10 secs in an attempt too disable it, it seemed todo the trick as i didnt go int Chakra chastise the entire BG apart from once when a warrior was on wich im guessing was a peel tool, Anyway midfight i changed too chastise manual with plenty of people arround too heal, once i was in chakra chastise it stopped casting heals, it let go a prayer of mending and a coupel other instant, but it wouldnt hard cast any big heals even though they was needed, So it seems the problem for me was indeed the lack of a 4 set bonus, Hopefully this is also the issue allot of others wer facing when it was "standing doing nothing" /fingers crossed, and now we know what the problem is we can work arround it till we have 4 set bonus.
Can anyone else confirm this?
