As an (ex) RGD coder from EiRR mod I can confirm that
A) Modding has been disabled (after being enabled for a time) for ages, long enough for Relic to crank out masses of DLC.
B) There hasn't been a real post on the relicnews CoH2 modding forums for ~2 months now.
C) Relic wouldn't bother with the Warmap concept from EiRR--they're only ripping off/making use of the persistency mechanic; vetted units that survive are available later--IIRC this was available way back in the vCoH campaign (pre OF/ToV).
EDIT: MEIN HUE, they actually copy-pasted the Warmap. That's it. I have officially seen it all, I have officially seen the bar set so low that the gap between it and the baseline is an airtight seal.
D) I'm rapidly losing patience with CoH2 and would really like modding to be re-enabled.
E) Did I mention the modding?
The only thing the map thing has in common with EIRR's warmap (from what I can tell from screenies I just looked up on google) is that it's a map and shows what battles you'll be fighting and where your units are. There are a shitton of games that have this. Persistency existed before EIRR too.
