Niara very correctly noted, that positive feedback is a valuable thing. Developers would want to know what changes were right and what's to keep during development. Let's make a list of things we like about Patch 6!

For me:
1. Dice!!! Love it now - clear as day for anyone unfamiliar with DnD, fun to roll and just pretty (people are already making mods for different dice looks)
2. Sorcerer class (obviously). Needs some tweaking, but everything always needs some taking.
3. New dialogues. There can not be enough reactivity, of course, and there are bugs too, but it's such a pleasure to see companions reacting to events happening with the protagonist!
4. New Shadowheart personality. Actually, have mixed feelings about it (keep waiting for her to snap on me, guess, I was traumatized too much in previous PTs) but glad we can save her now and she appreciates it.
5. New graphics.
6. Optimisation (serious boost to loading speed)
7. New faces.

There is more, but those seven things are the first that come to mind and that definitely has to stay!
