I think the summoning coop feature of this game is awesome. However, I think that the invading part sucks. I usually get wasted by the invaders. They are usually way tougher than I am and getting killed and sent back by them really sucks. I think I killed 2 and died prob 25 times. So now I mostly just go hollow so I don't get invaded, fighitng bosses solo. And when I do go human, rarely do I find summon signs for help anyway. Just beat the 4 kings and nito yesterday and no summon signs anywhere, but I was getting invaded a lot.
Maybe there are no summon signs because I am playing this game over a year after it came out. Makes sense I guess.
Example, someone invades me, I get ready as I can (my guy is ready for PvE not PvP), guy invades usually one hits me stunned then another quick hit for death with some giant weapon even though I have shield up. Or other scenario, I go to hit him then with lag all of sudden I am backstabbed wehn I am still on side of him.
So when beating the 4 kings, I guess I missed that witch summon because I went hollow and now I can't get her catalyst? That blows.
I think they should make it where you cannot get invaded unless you actually have a summoned partner to help you.
Also what could possibly be the reason when you summon someone and then they just leave right away? Do they think I suck just by looking at my armor or something?
