first game in ranked in a while

everything's going great! aside from a few missteps from teammates we're dominating and getting our mid and jungle hard fed.

fast forward to 50 minutes. we're still up on a ton of kills, but the enemy team has now farmed minions up to near full build. there's a tanky ryze, full build yasuo, full build corki, full build voli, and a near-full build AP nidalee. a few trades in i realize, hey we have to catch one or two of them unawares if we have a chance at beating them, as they're all late game monsters. everyone my team thinks they're unstoppable gods of nature and decide to overstay inside enemy base. i ping them to leave, they dont leave. i say leave the base now, they still don't leave. then the lategame yasuo and corki kill all 4 of them alone, and it's my fault for not being there, when i specifically told them to leave 5 times. THAT is how i know im better than silver. because i have the common sense to stay when it's a good time to stay and when to leave when its a bad situation.

i really hate that idiots like this cost me my LP because they think they can faceroll everything just because they reached full build first. when everyone's at full build its a VERY different ballgame. you can't just run in and faceroll them anymore. you have to plan. you have to grab other objectives like baron and dragon some more before you decide to fight head on, because let's face it, their team is probably one of the best lategame teams out there. they have lots of cc, tons of damage, and very good poke. do people ever get any less stupid, or do i have to play the no-fun freelo get insanely fed at 10 minutes champs and just carry my teams for the rest of eternity?
