I know I'm biased, but I'm just not excited for MWO at this point. Its not bad, I just don't see that it brings too much to the table beyond the meta game stuff. The sad thing is all the features that have been developed for MWLL that will never be in MWO, and will therefore never be experienced by a vast majority of MWO players. Tons of little simulation aspects and visuals that are greatly streamlined in MWO. I still can't believe that no one cares about mechs just clipping through trees as if they aren't there.
It also makes me sad to see the amount of hate by MWO players for MWLL. I read on those forums and it just blows my mind how much arrogance and ignorance there is.
Bryan Ekman is on public record as saying destructibles in the form of smaller props and some vegetation will be added. We shall see.
The one aspect of MWO map making I do like is the use of collision proxies around object and entity groupings that prevent, in most cases, the "tripping" or "stopping" of mechs. Their 3D artists have included the collision proxies in the terrain models.
One area I do not like is the ability of mechs to climb very steep terrain slopes. This looks and feels, from the cockpit perspective, to be unrealistic and bogus, even if it does enhance mech mobility and game play.
There is much room for improvement, over all.
So far ... so good.
