At present, Conquest has turned into:
Spam cheap crap to grab ground as fast as you can.
Then get the mortars ready.
Then when Phase B hits, call out the rockets and planes.
Phase C, just do more of that.
It isn't good gameplay and isn't the tactical sandbox we were promised. People have figured out that they can economize a lot better by just fielding a ton of fluff with a couple hero units and a ton of artillery. They don't care about losing these fluff units because Conquest doesn't penalize it. The 51% is becoming cancerous and it's becoming an artillery fest to pin any pushes, just as bad as anything I've ever seen in Red Dragon destruction.
I played one game of destruction last night (first time in the beta) and yeah, you know, it too is an artillery fest, but at least you can make them pay and players don't swarm you with cheap stuff because it adds up to a loss eventually. Oddly, it was a better experience mainly because there wasn't any spam. It was still a lot of camping and artillery, which is the biggest drawback of destruction, but who can seriously look at Conquest right now and not say the same thing?
The difference between the two modes right now isn't playstyle at all, its just income and since income is flat in Conquest, you get to spam all game long. At least in Destruction, you can deny them some income.
To be clear, I friggin hate both game modes right now. And I really felt like Conquest was going to be the no-brainer go-to game mode for Steel Division, but it is beginning to suffer from its own unique problems stemming from the map control and a brain dead set of 'I win now' buttons being fired behind a wall of cheap infantry.
