I've seen videos of people in Challenger playing Karthus jungle and im just wondering if it is still good even with runglaive and as a thing in general. Also is Karthus jungle just situational or you can pick him into any comp as jungle?
No.
You rely on the enemy jungler to not be smart enough to walk over and kill you during your first couple clears or on your team to be smart enough to help you if they invade you. I believe you go trailblazer and do not upgrade into a enchant and instead just build ap.
Good? Not particularly. Fun? Definitely. You need team help to make sure you don't die to an invade while taking blue, but after that its not terrible. Loss of Magus hurt a lot, but just build Trailblazer and go tear -> Rylais -> Zhonyas and it still gets the job done. Its also worth noting that you absolutely need Spellvamp quints in your runepage or it won't work.
I play it in normals with friends occasionally, but I would never pull it out in a more competitive environment.
He was okay when Magus existed. Now, he is just bad.
