Why kills isnt everything

http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1783529348/212949202?tab=overview We were down heavily (I mean jeez 42-29 is the ff20 score right there), but we somehow manage to pull off a win. THe 3 adc comp losse teamfight with the tons of thornmail, tank and a riven, but my god the map pressure was real. Sure we lost almost every teamfight, but while they were groupin as 5 dicking around in mid lane, Lucian would pop around the bot lane to push, they went down and twitch come out of stealth at top, all the while the rest of the team was able to push back mid. And it keeps going on like that. Loose teamfight badly, manage to get towers. 5 man push down mid got our inhib? Twitch just got your top tower and inhib and now is gunning for your nexus tower. Send 2 man (1man is going to get killed by suprerior firepower), Twtich stealth ghost blade away while Lucian is banging on your tower. In the end, we manage to win a 42-29 through sheer map and objective control with adc poppoing out of the shadow playing guerilla tactic with the towers. I mean hell the last fight was my team getting steamrolled mid as I stealth in through the open bot and ambush-ghostbladed their two towers and Nexus unopposed. So remember guys, kills aint everything, the map is.
