A dubblepoaster is me!
Fiddling around with the beta this evening... in the spirit of testing, I've been doing sidequests as I arrive to the areas instead of my usual (run through to Brutus/Merveil, then faceroll the sidequests after the fact).
I have no idea if this info will stay relevant, but I'm gonna list things I've noticed in no particular order.
-----
Act 1 waypoints have been moved around a bit. The mud flats WP is now in front the entrance to the medicine chest side area. The submerged passage WP is very near the mud flats door, and appears to be static now.
Submerged passage is one large area now. (no upper and lower) They made it a lot twistier; I hit a lot of dead ends.
Flasks have been improved across the board (so far). Mediums @ L3, Large @ L6, both giving more than they did before.
Early drops have been a riot of color. Plenty of sockets, plenty of links, and plenty of variety. I even have several chromatic orbs from selling trash.
The performance displays toggled by F1 have shrunk and changed position. They no longer overlay game data, and there's a third setting that only shows latency.
Latency in general has been very stable during combat @ about 100ms +-15ms. (In Tucson, AZ, 6Mbit connection, using the American gateway) There's been a couple minor pinches of desync so far.
A support gem is offered up prior to fighting Brutus, like it is prior to Merveil in the main game. Still got a post-kill reward, though the spread was very different than normal.
I have all my purchased stash tabs, but no guild status.
Chatters was slightly less of a jerk than normal.
I have not fiddled with the item filters yet, and probably won't until late Act 2.
