Is this the final UI for the inventory and looting system?

Ooh, final. That's a harsh word. But no, this is the T0 for the inventory and looting system. We will keep iterating and continuing on it. Obviously, if you've played Evocati through to now, you've already seen a huge amount of change around that UI. So we're always going to be iterating and working on it. But it's the one that is going live for 3.15, and hopefully lots of people enjoy it, and then we'll take further feedback and then continue to iterate it when we do T1 and T2 and so on and so forth.
