Well, many players (inlcuding me) HATE any and all PvP.
And what we hate even more is PvPers trying to force their play-style on everyone else, pressuring devs to make life harder for carebears (badmouthing us sheep in order to make life easier for the wolves. This has been going on in Eve Online and other MMOs)
So I very nearly cancelled my purchase when I read about mandatory PvP.
Especially since for a small game like this, it's more likely someone will find a way to hack it, and *click* eradicate the units you've been training for days.
IMO the decision to force everyone to participate in PvP is a grave design error.
