Carry harder. =/

End it before their carry team is fatter than you are.

It's a team game, and as painful as it is to accept and realize there isn't a lot you can do to carry people sometimes. I've lost games grossly farmed with some of the games hardest carries (TDL, Draconis, Silh) with 700gpm against teams smart enough to counter you, because if your team is much worse, you're more than likely going to lose. "Carrying" a team is only possible to such an extent. I've boosted many an account in my day, and by far the most reliable way to take over games is to play a strong early and mid game mid ganker. Bubbles, Deadwood, Pebbles, Hag, Pyromancer, Chipper are just a few I use commonly. People also seem to have a hard time dealing with "tankier" carries, like Armadon, Soul Reaper, etc. Again, you can never truly seal a win with bad teammates, but the easiest way to reliably win and have fun is to queue with a friend and play complimenting roles, such as yourself on a carry and your friend on support.

Hope that helps a bit, good luck!

A good support can do wonders for a bad team, try it; unless you only know how to play carry.

this. supports change games.

Yes, but in lower brackets 80% of the time you play support, your "carry" will be a total retard, leaving you worthless.

Best hero's I find to play is initators/heavy gankers (hag, pebbs, dev, legionnaire), or a carry with an easy escape/save.
