Breakages on every release. Is there even any QA? Any testing?
Friend list doesn't even update anymore, can't tell if people are queuing, in game or just sitting in lobby. Sometimes they're not even online when you know they are.
Khan's Ult doesn't even work anymore. You can be standing in their face and use it and nothing happens.
No consistency with shields. Some champ shields block certain things, others don't. Melee should not break through a shield, if Maeve pounces with the legendary to go with it, it shouldn't pass through a shield like it's not even there.
Ranked games are a joke. People join who haven't even unlocked all the characters leaving a team without a support character or frontline. How can someone break through ranks if they're consistently matched with a group of people who have barely played the game or just AFK and get destroyed by the other team? Especially the ranked games where there is no communication at all, the top person who picks the bans and first pick just picks randomly and then a character they just mess about with. What's the point? The only way people move up is if they carry their whole team. I don't even know how people do that with 150+ ping... which leads me to my last point:
For some reason OCE has a lot of players.. but ranked queue never pops. Just queue forever, so have Oceania players leak out into NA/SEA regions and play with up to 150-200 ping.
