I think those who want to remove DTV are just those who dislike fighting bots and are annoyed that there are so many players in EU7 who do that.
Theoretically these numbers could go to EU1/2, but practically they wont. Not like anything I'm typing hasn't been mentioned tho.
For my own part I always enjoyed DTV and Strategus the most. DTV is a place to play crpg while being fairly relaxed, which comes super handy to me.
I never liked EU1 so much because I usually end up with 70% of retarded teammates who run in circles and die like flees while leaving me alone to get raped as well.
While this can be fixed with clan,TS n shit, I still rarely enjoy it.
Strategus and DTV were always different in this regard, even brainless spamming in siege used to be a lot of fun.
I find it quite awesome that a PVP mod like crpg has a PVE element attached to it, sure remove it, best idea which comes up over and over again.
