When playing offline, you still get invaded by NPCs and still can summon white phantom NPCs. All I want is to play with friends without getting interrupted every 30 mins. If they can't be assed to implement proper matchmaking that takes gear into mind to eliminate PvP twinks and latency, to eliminate backstabs from front, then I can't be assed to respect such PvP mode.
I've been on both sides, where I would backstab someone from front or where we would both swing at air and both get hit. It's not fun, it's not challanging as an invader pr as the one who is getting invaded, t's just annoying. So tp save time, I just use lagswitch to make invasions go faster. To be honest, on my high soul level characters I don't get invaded at all. You know why? Because all PvP wanna be Pros can only gank low soul level players with their cookie cutter bullshit gear at incredibly low soul levels.
My 2c.
