It feels like this is a totally different game

With the season coming to an end and me stuck in Gold 5-4 I decided, what the hell let's go and play ADC! FYI out of the 5000+ games I have played in my league career, maybe 200 of them are ADC, a role I always avoided because it requires too much focus. But this season I can't get anywhere and I am deadstuck in Gold 5-4, while I used to be platinum 4 maining Evelynn jungle and carrying my solo ass to plat. This season it seemed impossible to climb and I also had less time, so like I said, I wanted to try ADC and guess what? With two fingers in my nose I am climbing.. Yes maybe it were just a couple of games, but let me compare this to things about 2 or 3 seasons ago.

Back in S5-6 when I got into Gold I got a bit cocky and decided I wanted to try something new, so I picked a different champ and a different role and I thought that I would easily be able to do that because well I achieved gold now, so it didn't matter which champion or role I picked. I got my ass handed to me so many times I went back into silver and back into gold and back into silver AGAIN, just because you couldn't just decide to play something else and think you are just as good, definitely not in Gold+, Gold actually meant people knew what they were doing.

Right now I started playing some ADC and the sad part is, every opponent I have had feels just as random a player as myself. I even manage to outfarm a lot of my ADC opponents, which was completely unthinkable in the past, no way you would outfarm a real ADC main. In the current game it feels more like whatever I'll ADC and see how it goes and I have to admit I quite like it, hanging a bit, killing some creeps, watching my ass not get killed and things seem to be going alright.. This is ridiculous, how can a jungle main decide to just go and play ADC in Gold 4 and get away with it? Please tell me. Even if it's just 5 or 6 games; in the past I would get absolutely destroyed and would solo lose the game because of lack of presence.
