Move Traceable to difficulty increasing mods section
TC is a mod that always increases difficulty and is quite similar to HD. Given we even have diffcalc/pp considerations for it it's time to move it to the category it belongs.
This doesn't cover any other mods that might need reshuffling too because TC is the only one that has actual impact on difficulty-based leaderboards (as in pp) and some people are actively playing it for the difficulty increase and not just as a fun gimmick.
After a quick search turns out it was difficulty increasing from the start but was moved to fun in review https://github.com/ppy/osu/pull/3569#discussion_r300085523 but I don't really agree with that.
Also as far as I know multimods don't do anything anymore?.. I've put it into HD multimod for consistency, but can move it to be separate if you want
This change affects the solution of at least one live medal. Blocking pending consultations as to whether the change is acceptable from that angle.
TC is similar in difficulty increasing effect to HD so it should be fine if HD is allowed to be used for the medal in question I think, though I'm not aware which medal you're talking about
At least one unavoidably affected medal is hush-hush, so naming it would be spoiling.
Relayed relevant concerns internally, will wait for a conclusion.
No apparent objections from the medal angle.
Is it good to go in that case?
