I like this change. I played on Pokerstars originally and never noticed the slow dealing speed. Then I moved to Full Tilt for a bit, and when I came back to Pokerstars, I thought maybe the software was broken, or like a kids toy that needed its batteries changed.
Even if some players are surprised now, I think after these changes have been around a month, players will like them and won't even notice them. I've never seen a 2+2 thread that said, "Hey poker site xxxx! Stop dealing the board cards so fast!"
I really like these changes.
Note that I am primarily a ring game player and a CAP game player, and this post should be taken with that in mind. I can't really comment on the Super Turbo SNGs (where the change is more significant because it may actually alter the game play).
But even if you continue tweaking the super turbos, please leave the ring game changes. All-ins feel much more streamlined now.
