It is easy:
- better balance - self explanatory but it will take the majority of work
- dev communication and more updates - like pls man
- matchmaking - even with a not so big number of players playing I can already see it working
- block feature - blocking annoying players yelling slurs and other individuals to never playing with them ever again
So far the biggest problems in my opinion. Even the events can wait, before these get resolved, so good luck devs.
