The amount of cripple, immobilize, and chill getting tossed around is way too high. In teamfights it's pretty common for me to be permanently crippled with immobilize also being far too frequent for how punitive it is. This has resulted in a situation where the only way to be mobile in fights is to play classes with heavy amounts of teleports, leaps, and attack avoidance. Classes that lack those 3 things are non-competitive. This heavy amount of soft control stems from the superfluous amounts of soft control effects certain classes have, there are several builds in the meta right now that can apply perma cripple with frequent access to immobilize and in some cases chill as well.
Below is a list of recommendations. The list was created by looking for soft control sources that are both common in this meta and are nonessential/superfluous for the affected builds or weapons.
Sanity is for the weak minded
