9.1.5 has brought more people back because we can finally play alts again. Also playing the other 3 covenants can change a lot of game play along with giving people cosmetics to chase.
Mage tower is hard and its sweet. Probably the highlight of 9.1.5 for sure but its weird that its not available all the time.
As long as they KEEP these QoL and make more in 9.2 its great. If not, its really a short list in what would be considered low energy as far as other patches have been concerned at least for me
