I like how our half of the lane counts as OUR TOWER for him.
Anyway I did nothing in lane, but there was really nothing to do, I couldn't dive jarvan and hope lanewick could follow with damage or CC, simply because he didn't even have exhaust (and because I was stupid enough to dive a low life jarvan and hope lanewick would do anything). If I dive rammus he goes defensive stance and jarvan + him beat on me, and jarvan had an exhaust. If I dived jarvan rammus would just defensive stance + taunt, get exhausted and die.
After a while it didn't matter, I was under CS'd because he made sure to use Q on whatever minion I was going to last hit, kept pushing the lane, and when jarvan and rammus hit 6 they could just double ulti and kill me (being the weakest due to being undefarmed and the only source of CC in lane, they knew warwick could do nothing about it).
TL;DR, lanewick is bad unless you're playing against 5 people with zero CC, which isn't possible.
EDIT: Last game of awesome denying. I queued with this green fellow above me and denied the hell out of veigar and tryndamare. I remember looking at CS rates and noticed me and vlad (oberondark/yodamaster) were each at 21/20 CS while veigar was at 7, and he was solo, lol. I also managed to miss my ultimate twice as malphite, but we won anyway since their main source of AoE damage was denied to hell and back, and due to the fact their only source of tankyness was a jungling trundle, while our team had garen, malphite and vlad.
Anyway, should I buy Jarvan now, or keep for Renekton? I have decent practice with Renekton and he's good during the whole game, I never really played Jarvan.
