10 man raiding for mythic

Not reducing the group size so we go back in time (where 10m and 25m had to be balanced differently because mechanics in 25m were absolutely 100x easier in 10m, hence the puddle example).

Man when I think back on even cata raids, which were for the most part bangers, them bosses had like 3 mechanics until you got to like the last 2 bosses lol.
