I've played a bunch and I like a few things, and dislike a few others...
I think it is good that your seeing some people trying new things. Not every game on riverside needed to go to the Citadel and shoot across the river till the last few pushed on each other. On the other hand watching a atlas try to run across the high bridge in riverside is funny.
Disconnects. These seem way higher. I went from seeing them every now and then to fairly common. Also people seem to be slower of the mark. Game time you can look back and see 2-4 mechs still in the starting area not moving, but later in the game they got out and involved. I don't think this is bad as it seems to be affecting everyone equally.
Fast Drops. Sunday morning I was dropping heavies to try to finish my Marauders to Elite and the heavy queue was 42%. I was waiting 2-3 minutes before drops. I swapped to Lights, and assaults after I got them completed and was dropping nearly instantly, 5-10 second waits for a drop.
Player shooting. I'm more careful about not crowding fire lines. Some of these new guys have no concept of don't shoot the team. Same with the random trigger pulls right after the drop. Shoot the rock all you want, Don't shoot the Team.
Map Coordinates. That's all. They are not tough to figure out for most.
Grouping up doesn't isn't something some people want to do. The rolling ball of death is now 5 mechs if your lucky. Lots of potential Steiner recruits also. I can tell by the wall that Atlas is way over there, stomping Scouting around by himself.
Overall, I think its been great.
