Botlane hardest to carry with (discussion)

We have been duo'qing almost exclusively for the last year. Prior to that my partner was a high D1/Masters support main that went ADC to help teach me support/the game/main a new role and overall we've had a ton of fun improving as a pair (I went from scared of leaving my turret to having him bring out the best in me lol wise). We never really "hardcore try-harded" as I really had a lot to learn, esp mechanics wise & still wanted to have fun. We took a hiatus for a few months (I quit for a bit) after getting to mid-plat and have returned to lol this last fortnight. Gotta say, however, that REGARDLESS of how well we lane and team fight it has become** NOTICEABLY harder and more frustrating to use our lead botlane and transition it into a win** - understandably we (mostly I) could be doing more but is this generally a shift in the meta/standard atm? Because from experiencing other roles they are a lot easier to snowball with (ofc the toplane meta). We are finding the BIGGEST DIFFERENCE from our ranked games previous to my break to now is that our team is **CONSTANTLY **fighting. Vision means nothing, objectives and pushing waves out are also a last priority compared to getting kills. My sweeping, timing of summoners and prompts of dragon timers etc go unnoticed more than ever before. I sometimes go to my allies to help peel them from getting caught but despite a ping back they always try to turn the fight into a 2v5. And despite my partners individual strength of play he often gets prio targeted by the enemy (my peel alone isn't always enough) and each game is just a huge mess of us noah arking and then the enemy. Either I have a better understanding of the game than I did before and am seeing it in a different light or league has evolved into an even more blood thirsty game than I remember.

So this leads onto:

• is it generally agreed that botlane have to rely on their team MORE than any other role & is the hardest to reap the reward with despite your success in lane?
• maybe we are not adapting properly to our teams - sometimes I personally feel doing the "right thing" such as "de-pushing" a wave or preparing dragon isn't actually the right thing at all. That maybe I/we should ignore all this and stay with my rabid team-mates and try to make every team fight that occurs at 30 second intervals more in our favor?

NOTE: this is more my (the shitter support's) thought's tbh. I have talked over this with everyone I know that plays but would definitely appreciate an outside opinion. This is just another hurdle for the moment that I am personally stuck on. My partner is obviously still in diamond on his main (and he's not here to eloboost, we are a duo and we're both learning to a lesser/greater degree) so the reality could quite possibly be that I am the shit that balances the scale >.< It just wasn't this difficult before and I feel that we've(me) actually improved as a botlane!
