How long is hyper-mobility creep going to last
Taliyah's ult. Tahm Kench's ult. Reksai's ult. Aussie's E. Bard's E (to a lesser extent).
For the past 2 years, riot seems intent on pushing a lot of champs on us that can get across long distances on the map in short order. That's literally half of all champs released since reksai at the end of 2014. While it was interesting once or twice, if you keep this up riot, we could have a team comp based on a team teleporting halfway across the map on a moment's notice. The only reason we don't now is TF can't really ADC... however with a TK support or top, you could probably build the basis of one without a hyper-mobile ADC.
I mean just before this kick started, people were complaining about mobility creep in the context of short dashes, blinks, and Kalista's passive. Now we are getting a worse form of mobility creep that lets a lot of champs dash halfway across the map. Sooner or later a blitzkrieg comp will become tested based on zipping the entire team to one point in a hurry. When it does, you have to worry about what will happen to the game if it is a viable option to run.
I may not be high elo. I may not be in the LCS. However the idea of an entire team being able to outmaneuver yours to take objectives, particularly if they have a vision advantage is a frightening prospect for the league. Splitpushing and 3-1-1 splits would be effectively dead against that comp. That comp would have very high pick potential and could put a lot of team members on the one guy on your own team is out of position.
