Im convinced that on console, every fucker that's kills me from afar with an smg is a Chronus user.COD. Used to dominate. But a combo of skills getting worse, ratmazy maps and SMGs everyone uses that are accurate/low recoil really sunk my game as I used to pick people off with ARs and LMGs from open distance.
I used to play Halo games at Heroic difficulty minimum. Had to move down to Normal for Infinite. Could be I'm in my forties now aswell though.
And you can for the most part always get it back. Though GaaSy games with shifting metas can be a little tougher.You get rusty in every game that you stop playing, so this applies to everything. Not sure how this is even a question lol. Anybody says that they don't get rusty in a game that they were good at and haven't played for 6 months plus is just lying.
Oh of course you get it back, even within a few hours of play (depending on the game of course). You just need to actually give enough shit to lose the rust. For me personally, when i quit a game and get rusty, it's usually when i am burned out on it, so coming back and losing the rust is pointless, i don't want to play the game anymore.And you can for the most part always get it back.

I'd wager that a lot of the people who say COD were never that good at COD to begin with. In the old days with the far lighter SBMM and the ultra-casual-most--not-even-wearing-a-headset players it was just a different game. If you had even the most basic of skills and a half decent 3+ person stack you could go many hours before running into a challenge let alone eat a loss.
