I will say this:
On Alpine, the new spawn points have all but eliminated cap rushes. So far as i have seen in the few pugs matches I have played.
I should mention i only play assault before getting to far into this. I dont play conquest, even with my 12 JJ spider
I think the intention is very good, i think the execution is under review, and will be polished later. it took them a long *** time to do this, probably wanted a huge amont of data from the heat maps before doing the work.
I think river city is much improved on assault, as is alpine.
I think terra therma- it depends on how competent your pug is. i had a match where the lance on the perimeter was an atlas, a misery, a battlemaster and a dragon. They went around the edge to cap because thats where the path led them. The rest of us were blown to bits in a 12 vs 8 where our assaults were nowhere to be found. I had a match too where we all sort of meandered towards the one side of the mount doom, and then flanked the enemy and stomped them bad because we caught their mediums in the open right off and got a significant numbers advantage. This map needs a revision, the matches are deffinatly not all about marching into mount doom anymore, but they are also some of the most lopsided I have seen in a long while, one way or another depending on how your pug lotto turns out.
Alpine: might need a little polish, but overall I like how it has turned out. Makes scouts actually useful for more then 5 seconds, and makes deciding on where to move to( NO matches have reverted to radio tower standoff as of yet for me) to set up defenses or advance on the enemy much more important.
River City: much better, havent seen anyone successfully cap rush yet. No more yin/yang base race. A lot more opportunity to use the terrain for advantage and cover etc.
Forest colony: I see nothing different, did they even change this?
Frozen city: Mostly not enough to alter peoples behavior on this map. The one side mostly just zergs to the ship. I see more tunnel running actually though, not that that turns out well usually.
Tourmaline: Jury is out for me on this. Does seem to make scouts run into each other more, but with the abundance of streakboat jenner hero and streaktaros used to counter them the last week, I think the end result of this one will take some time to see.
Again, this is me playing pugs on assault. I can not provide feedback on conquest. Or premades.
As for the bombs, eh, i got caught in one with my spider by accident when I ran over the hill(couldnt see smoke) at a bad time haha, my arm armor ate it. But other wise most of the time it is being used pretty tactically IMO. Lots of times used to break up a zergfest blob.
