From my experience, it sucks. In DS1 you only get invaded like that once or twice before you beat the boss and are safe. Or just don't use Humanity. Boom, safe again. In DS2 you're never safe. Human? Get invaded. Undead? Get invaded. Boss defeated? Tough*****, get invaded. What's that? Twinks don't exist? Hello, Agape ring! Now you can progress and twink to your heart's content. DS2 has such a *****ing hardon for pvp it's ridiculous. I'm so glad my first playthrough was mostly offline. Initially I just wanted to avoid spoiler messages, but*****ty invasion mechanics definitely helped keep me offline. I was kinda bummed I wasn't able to farm bosses co-op and collect gear, but with soul memory there really wasn't much point to it.
