Forgotten Hope 2 is not pushing the limit on the realism side but staying right between the fun and serious bit.
However we do provide the ability to each player to play without a hud with a simple editing of a txt file within FH2 (I forget how exactly it was done.. and no idea if it's still 100% working :S )
How do you mean: more classes promotes better teamplay?
Mumble support, cool idea but no idea how that's implemented into FH2. I could ask the rest of the team on that bit..
I am pretty sure they did not have a Range Finder in the binoculars 70 some years ago, thus being kinda unrealistic suggestion
What is TG?
You indeed can't revive players, and the standard FH2 server preference setup has incapacitated time at 0 if I remember correctly, so normally you don't get to experience that incap time one PURE FH2 servers..
