For me, toplane is very closely tied to the jungle.
Early jungle is just so damn impactfull and busted atm, and it really limits your options for top, since top is a very vulnerable lane.
You can't excert any early preasure or you give a free kill to their jungler, unless you play one of the few super save picks. This heavily reduces the viablillity of alot of champions that would rely on early preasure to establish lane dominance and snowball from there.
I can beat tanks, even orm, with most bruiser quite well, but only if i actually get to play it 1v1. As soon as their jungler shows, i'm done for, because i have to conistently keep the preasure up to win the matchup, and they have good CC to set up ganks.
In the old days, even if you pushed the to their tower as a champ like renekton or darius, the opposing jungler would think tiwce befor ganking you as he would be behind in level and probably not fullhealth.
But now, even stuff like jayce jungle runs unto your lane at min 3 beeing 1 lvl up on you with doublebuff and fullhealth, and you can't even ward because the usless trinket only has a ~35% uptime early on.
The other issue is that impacting the rest of the game as melee is prettymuch impossible unless one of 3 things happens:
- You're fed beyond belive
- You're a tanky CC bot that set's up things for your ranged gods
- The rest of the map is even or slightly in your favour
Bur as soon as other parts of the map get a it fed, you hardly can do shit, and if your botlane snowballs, you also don't matter anymore, you can just watch them win the game while beeing at best a distraction in comparision.
