If the BPM is less than or equal to 125 BPM, a drum roll's tickrate will be snapped to 1/8th, not the default 1/4th. This goes against the slower tempo of the song, so I think they should be avoided, and mappers should be told to avoid them in the RC too.
I propose adding the following guideline to the general taiko ranking criteria
This doubling doesn't occur when the slidertick rate is set to 3, so its exempt. I propose a guideline, not a rule, because maybe there are certain cases where the mapper might want to use a drum roll, like 1/8th or 1/16th rhythm. For the most part though, mappers shouldn't be using drumrolls at these BPMs.

Sliders/Drumrolls shouldn't be used when the BPM is 125 or less. The sliders' tickrate doubles at these BPMs, creating a fast rhythm that's unrepresentative of the song's tempo. This does not apply if the slider tickrate is set to 3.
