Queue and Quit / Downed, Instant Disconnect / Solo-Drop, Downed, Disconnect
We need punishments for players that queue and quit as well the players that go down and instantly disconnect. It ruins the experience for two other players each time.
I would suggest 15 minutes should be the minimum with increasing returns. So if you do it once then you get 15 minutes of not being able to queue. Do it again within a few matches then you get 30 minutes. So on and so forth with no preset limit to the amount of time a player can be penalized.
If you queue and quit or disconnect instantly then obviously you had something more important to do, so go do it. A 15 minute timer shouldn't matter much to you since obviously you're busy. It'll wear off while you're out being productive... but if it bothers you then obviously your intention was to just hop into the next match and potentially spoil the match for yet another 2 players.
Now for solo-dropppers, solo-dropping spoils the game for your teammates as well. If you want to play a solo game then go play something else; because when you queue in Apex you're agreeing to play a match with at least one other player as a team. Which is also a point that applies to the above.
Players that aren't the jump-master shouldn't have the ability to jump solo or split off from their team until they're a certain distance from the ground. Going over to a nearby building or compound so you can loot and join the fight with enough resources to actually stand a chance is understandable. Especially if the chosen drop-spot is highly contested; but just dropping solo on the other side of the map because you think you're the smartest, the best-of-the-best-of-the-best-with-honors, or because you don't like where the jump-master wants to land is simply poor sportsmanship.
These types of behavior should not be acceptable regardless of if it's casual or ranked because there's no reason one player should be allowed to ruin multiple matches for multiple people without any consequences. Like they say, there is no "i" in "Team".
