The last thing CoH 2 needs is more factions.
CoH 2 is about the Eastern front, I always found WFA to be out of place and immersion breaking to be honest.
They could add some Theatre of War stuff, your suggestion of the Battle of Kursk is great and should be a no-brainer for Relic.
Regarding multiplayer I'd prefer commanders instead of new factions as a way to introduce more content and variety. For instance a Finnish Commander and a Soviet Baltic Marines Commander or a Polish resistance commander, all that would be interesting.
The Caucasus and Baltic theatres haven't been touched much by Relic, there's a lot they could add from there.
me too, when they announced WFA i said: why? was CoH2 on the eastern front, but eventually i said very good, i really enjoy playing as USF, even if i usually play as the red army.
Thank you for agreeing with my idea for Kursk! I'm so excited for idea of fighting that battle!
For the multiplayer i think that you're right, especially USF and OKW that have few commanders Relic should make new ones for them but i don't see why don't add new factions, i wrote before that i don't think that they should be added soon, i'd say May-June or at least July (like WFA in June), firstly i think that Relic should finish what they left uncomplete: the eastern front. And why don't follow the Western Front, a ToW pack for it? And then that faction pack, i'd prefer Commonwealth and Italy, as WFA is set in France, Belgium, Luxembourg and Germany, this pack should be set in Italy and Balkans (i hope Southern France too, I'd call it Mediterranean and Balkans Front Armies, it sounds bad but it's the only idea which i have for calling this).
I think that Relic should do new commanders for Ostheer and Red Army too, the Ostheer should have a Finnish Commanders and why not Romanians and Hungarians. An Italian commander for Ostheer? I'd say no because they weren't as incisive as finnish, romanians and hungarians even if italians had great losses of men and material in Russia.
For the Red Army i think that one of the most suitable should be a commander with the soviet navy support.
Caucasus and Baltic? For the caucasus i don't think they'll do something, Case Blue has been done and there is nothing for the Caucasus, the only thing i think they can do is a map (Majkop, Baku or Novorossijsk).
For the Baltic i hope they'll do something in the future, a possible "Stalin's Ten Blows" pack which includes the offensives in Belarus, Baltic, Ukraine, Romania and Poland.
