General Player Courtesy

Honestly I feel like I shouldn't need to say this but I see things like this time and time again and I feel like, as another player playing this game, some things should really be done just purely out of courtesy to make the game better for all of us as a whole, and this one I see more and more often for some reason, and that is:

If you haven't played the game in a helluva long time, like let's say 2 months+, could you please play a few Co-Op games before jumping straight into PvP? I just finished a game where I was laning against someone who apparently hadn't played for a while and ended the game 0/10 with only 42CS. I dunno about you but if I had that on my team I'd be hella frustrated. I honestly feel like people who do this should consider a few Co-Op games purely out of courtesy so you don't ruin the fun of potentially up to 4 other players. Of course you don't absolutely have to, but it still helps a ton with getting back into the flow of many mechanics like CSing or simply hitting skillshots.

Personally I'd go a step further since if I were to come back after 2 months+ I'd probably do some research on what has changed or how the meta has evolved but I can still understand if this is too much dedication; I do this since I feel obliged to as a player in a team game but I guess this is subjective.

Not really here to rant or complain, just something I feel I should speak up on.
