"Full of" isn't quite accurate
But they are very present (both in top 7 junglers at worlds), for a build that really shouldn't be working at pro level in the first place (unless y'all are trying to shift talon and qiyana into bruisers, but I don't think that's what's happening)
And the other super-prevalent champs are all using some form of draintank mythic. I'm definitely biased bc I don't like the playstyle, but the two draintank fighter mythics have completely crowded out stridebreaker and triforce.
Again, Goredrinker is OP. It's getting nerfed, especially for assassin types, in 11.21, so that's at least a decent push.
But even still, Talon and Qiyana were both buffed quite a bit heading into Worlds. Qiyana was specifically targeted for pro-focused buffs.
FWIW, Qiyana hasn't only seen Goredrinker builds. The last time she was played it was full Lethality. I don't remember how many more times that happened, but with only 8 games played, that's a sizable percentage.
