Wait for the stream about the upcoming changes and improvements. A lot of what you listed is already on the list of issues to be addressed.
The 5 subs are there too, but honestly, there are far bigger gameplay problems right now than worrying about subs. And realistically, how often do you even have time to make subs when playing in the upper tiers? Hardly ever. Start making subs and there’s a decent chance you’ll concede while you’re still trying to find the right player, let alone repeat it for 4 others after that.
I’d much rather see the devs fix the broken ball trapping, which actually costs you games, than increase the number of subs. But hey, priorities, subs!
Lastly, some of the recent feedback was also asking for some old tunes to come back, so at least we got one timeless classic.
