Went through Alex normal for the first time with 3 FC friends last night.
One friend had done some research beforehand and explained some mechanics and we met a few helpful players that called out key mechanics in the chat box as well.

We two shot A9 and one shot everything else albeit with some deaths and general messiness. I'd say the tuning was fine. Even with making mistakes we were able to recover and carry on to victory in most cases with 2 new healers (myself and a FC friend) in A9-A11. (for A12 we had another FC friend who had cleared before in one of the healer spots).

A11 was the messiest. 1 of the DPS accidentally released after being KO'd by the active time event but we still pulled through the second half in spite of only having 7 players and several more deaths.
