yup, people want 4-5min speed runs (namely for animus). Considering the hundreds of runs you need and hours it takes, you'll want 4-5min runs over 8-10min ones (unless you want to take that masochism to whole new levels).
Was really looking forward to the animus change, hope it is sometime not too far away next month. As their excuse of "not many people do animus" answer is somewhat obvious if they look at what they made available already ingame >.> (namely levi clears and t7/8 clears)
