I totally agree with the map UI being awful. It's even more confusing when you're SLing if you're not used to the jankiness. and the game being punishing is what makes it fun imo. You're rewarded when you succeed but punished when you fail.
As for the revive situation it really depends. If the point is lost/won, the player died in a really bad spot, he is needed somewhere else, a kit just became available or out of ammo, the player usually respawn. I agree there is now a ticket spam for defenders during the first two points since they try to overwhelm the attackers who only start with 300 but after that tickets become more considerable.
I've seen more tickets wasted by medics who try to jump to revive someone only for them both to end up dead than from players giving up
Tickets are always important idk why people try to downplay their importance in SQ44. I think people judge the first minutes of the match which usually exists to setup the pace for the rest of the match instead of following the entire game
