At first it may sound like a dumb idea, but they won the "Make Arma not war" contest, this is also so far the only addon for Arma 3 which adds tons of additional and realistic content. It would be fantastic to see a check box with RHS Escalation in DLC list for Arma 3 :D IMHO it will make this big addon far more popular and more people will play Arma 3 using this content, more servers will have support for this addon as well. (It will also update itself with the game, and keep everyone else updated).
I guess that could be discussed with RHS team, as this addon most likely will never appear on steam workshop otherwise (probably because of it's size or messed up policies of Steam Workshop), that's quite sad :(
Currently there are so few populated warfare servers (CTI) with RHS Escalation on them, which is quite sad too :(
In my oppinion this Addon deserves a lot more! :D
