I don't care how good you are, you can't carry teams this bad

When you pick Hecarim jungle because the enemy team doesn't have slows and your team needs initiation. When every gank you make nets a kill, but 1 or both of the other lanes die as soon as the enemy team sees where you are. When you're 5/1/1 and total kills are 6-7. When, despite being a jungler, you're equal in level to the enemy solo laners and have a 2k gold lead on everyone else in the game and can 1v1 anyone with ease and can with a 2v2 with any combination of allies an enemies, and could probably win most 2v3s and 1v2s. When you're on Hecarim remember, so you're an excellent split pusher who could easily take down turrets and get an inhibitor later in the game. When you don't SAY anything all game other than "can i get 3 autos for a leash at gromp" and "gj" after your ganks.

I don't care how good you are, you can't carry a team that's so bad your 4 allies all vote to surrender at 20 minutes even though if you keep up your current pace you're going to be able to 1v5 the enemy team.

Disclaimer: This is a rant where the above literally just happened. Don't know about 1v5'ing but when you're fed enough that you literally just 1v1 killed their top laner then almost 1v1 killed their mid laner (lissandra flashed + clawed to get away), your team should at least give you the chance to carry. Especially when you're not telling them how bad they are in chat (I literally said nothing apart from the 2 above comments all game).
