Oh yes I remember that too, as I was also one of those guys. If you equip low damage talis, but enough health and do it on manual you can get massive numbers of effects in one single run. I would assume this recent event could be done in less than 10 runs, but you need a lot of time and it is fascinating in the beginning, but also very boring in the end. Moreover, I suggested to give better rewards if you do it in less than X, less than Y runs (maybe double, triple the rewards?) but there was no interest in implementing this. So this time I did it on autoplay and I am still happy with this very low number of runs needed! Only sentinel Anubi had this "tatical" talisman setup with low damage output this time.
Actually I am still pissed because of march 1st, I even sent a ticket because of the update and also asking for a compensation, but there was no reply. I sent a reminder about it recently, but probably there will never be an answer!
I even think about converting the rare soul frags into precious ones, to avoid the ripp-off losses of 90 rare souls!! But the legendaries still hurt a lot more! 60 legendaries! MAN this was so rude and completely unfair, especially for us Europeans!
