I'm aware there are one known Ithziri armor user that has unlocked all 9 tiers and a few others that at least a majority of their unlock completed. I'm curious about which trees you chose to unlock, how far down each tree, and the rationale for your choice.
Somewhat relatedly: I recall talking to Aurach once and he noted a GM reported the possibility of offering a free tier unlock reset at some point in the future. I tried to find this information on the officials, but you know how that goes. Can anyone else confirm they recall reading this as well?
