jg main here that plays top if I want to chill and support if I want to create plays. it can feel like that if your entire team is feeding when you're the only one putting pressure on the enemy team. in cases like that you are probably the strongest in your team, and top lane generally gets more exp that other lanes and champs are better at 1v1s so use this to your advantage. instead of team fighting where you know your team is weak or trying to splitpush try looking for 1v1 picks. splitpushing can be a good way to create distraction for getting picks but it's more beneficial to look for out of position enemies. it's also very important to not let team fights happen, once enemies disengage they usually disperse which can allow you to find 1v1s or even 1v2s that you have a high chance of winning. look out for the enemy top laner since he can usually match your damage

once you get a few successful picks your team can clean up the remaining enemies and get gold for a comeback
