Yes it's a total disrespect in my view at least, demanding admins to change the realms they had worked for into features in other players' own interest/favour without even thinking about the impacts it may cause in a deeper prespective (I'm not directly accusing you though). So on your 7 years straight as a warmane player they didn't make any PvE realms and do you think that today is when the magic will really happen with just one more topic? Also don't judge me on my joining date. I made my first char in 2012 on Deathwing (not old like you I guess but doesn't matter). This is just another account I'm using that I recently have made. And again, you are telling me something that you for no reason claim without being sure, and this time I'd like you to answer me without dodging - where have you seen that sentece about the majority of players being PvE players? I mean, yes, any PvE players who totally hate PvP will beg for a PvE realm, but how can you assume that this is the "majority", especially for Icecrown??
And your last phrase just made my day, basically you're saying it's not wrong to eat apples or oranges but you can't eat any fruit. World PvP was always a part of WoW, a part where million players enjoyed the most, and being able to toggle it off is yes, removing a big part of PvP. Then the only place to PvP for fun will be battlegrounds, where you will highly fall into the risk of being camped in graveyards because the other faction is premading.
The big problem here is that some players are too bad to defend themselves from any harm, not knowing how to avoid ganks either, then they all come here with tears for being camped some minutes in their lives, begging to turn PvP off, as yes, it's poor.
