The difference, as should be blindingly obvious, is that Group A have no choice about "interfering with" with Group B's game in this tiny nebulous way, whereas Group B were actually going out of their way to **** with Group A.
What percentage of habitually Solo/Mobius players do you think really give a tinker's cuss about "affecting the BGS"? 10%? 5%? 2%?
I KNOW it's not about roleplay. That's just the figleaf that the griefers you're acting as an apologist for have been pointing to to excuse their griefing.
Lol, Jesus kid, simmer down.
Fact remains that there's a significant enough amount of people in Solo/PG that yes they have a solid enough effect whether they care or not. It makes Open players a little exasperated when their hard work is entirely nullified by clueless people who just don't give a "tinker's cuss". Do I think the PvE groups should've been infiltrated by PvP players and attacked? no, actually, I don't. I don't condone that sort of thing nor will I ever. I play in open 90% of the time, while occasionally switching to this forum's PG to play with a friend who does not like open. Anyway, I'm in open much, much more often than not and really? griefers are not nearly as much of a problem as you seem to believe they are.
I PvP, myself, but am I a griefer? I don't believe so. In fact, I go out of my way to protect people like yourself in open if they are under attack or need some help. I'm a defender. But I'm also an enforcer. I catch you doing something illegal or undermining the Empire? I'll give you a chance to either drop cargo or highwake out of the system. If you ignore my single warning, I will kill you. That's not griefing, that is playing the game. If you think gameplay like that is griefing then honestly, kid, stick to single player games and leave online-only multiplayer games to people like us who can handle things being a bit unpredictable, ok? thanks.
