Dark Souls 2 reminded me that it's OK to summon, don't let people shame you into a frustrating experience. If you wanna bang your head against a boss until he's dead that's fine and most would say the "real" way to play these games, but if not, just coop and be done with it, that's fine too. Get your fun back. These games are not just the bosses, and that's coming from someone that soloed every BB boss (even if now I know many were bugged) and is now summoning a lot in DS2 because you know what, I just wasn't having much fun and now I am again. /shrug
Although to be fair to BB, for whatever reason there seems to be less "summon shaming" in it compared to what I saw in DS1 / 2
