Wraith is a cunt, too, but I've encountered way more Krakens.
Of course, a lot of the issue has to do with there being a medic who doesn't understand their position. I've played a few games just last night where the medic tried taking on the Monster by themselves instead of doing their job.
In fact, that is the most glaring problem this game has. The idea of everybody having a set role that they have little control over was fine, in theory, but that's not how people who actually play FPS want to play. Everybody wants to be the assault or the trapper and I noticed most games saw the medic and/or support drop out midway.
