Did I play too passively? (No bot game)

I tried an actual game in summoner's rift and while we did win... the score I had was very poor in my eyes. I had 1 kill, 4 deaths and 4 assists as Lissandra. Top lane had me and a Riven with Kog'Maw as our foe. I didn't gamble getting too close due to ranged bots killing me before. The last two deaths I had was focusing on the enemies Nexus when it was exposed. (Match history here: http://www.leagueofgraphs.com/match/euw/3125720638#participant8 ) What should I have done to improve? Also... why does Mordekaiser's ult not work on enemy champs if he doesn't get the kill?
