I propose a solo player campaign game mode in which both veterans and newbies could benefit in.
Basically allow players to play the solo game mode to gain some campaign exp every week or silver/tech points (Assuming after merger).
It could be something simple as defending a objective against 3 waves of enemy. you have time to build defenses and stuff. But in order to avoid abuse maybe make the Objective like a large area rather than a small building. Also some narration along with some story telling element would be cool.
I do not expect a fully fleshed out campaign rather a short game with some good narration and general historic lore would be cool.
