"Mobility Creep"
List of champs who didn't get a dash on their rework
and now 
Some of them where minor reworks and some major. I just think the "mobility creep" hysteria blows the situation out of proportion to a degree. Not saying there hasn't been a creep... just not as much as some make it seem.
People don't consider power budgets, ranged vs melee or difficulty level.
And about the power budget: People always just bring up the fact that an immobile champion can't escape as well as a mobile champ. That's absolutely true. This doesn't change the fact that a lot of champs with dashes tend to be melee champions aside from a few
They also trade things like hard cc, defense, comparable range, and their ult.
If you're playing an immobile champion, you are usually trading immobility for range, aoe, aoe cc or extreme late game power.
Look at
ffs. This guys R targets every enemy champion on the field from anywhere; even from fountain. Talk about safety. That's madness. If he was a recently released champ people would lose their shit. He also has aoe CC and aoe damage in his Q and E. He's even expected to die, having an after-death passive.
is also a good example. Lots of AOE and a revive passive (expected to not get away).
Also, do we include champions like
or any champ with decent movement speed uptime as having "mobility"? They're able to return to lane faster than plenty of champions with dashes btw.
There is an idea of balance. I think people just use knee-jerk reactions to what they see/experience in a recent game and want to complain (I do the same thing from time to time).
I just don't think there is real consideration for how these champions are made.
Got more movement speed more ulti range and a mini dash.
Lost movement speed but gained a dash and a teleport.
Gained movement speed and better dashes.
gained asstons of mobility.
gained mobility.
...need I say more?
is the only one that's more "grounded"
^ This goon squad is very effective at hit and run tactics, kiting and repositioning is no problem, and that can be pretty polarizing when they are against older champs like
,his E range is not even comparable with the old Q unstoppable dash,both of them ended up having less mobility than pre-rework
