There's something I'm missing. At the start of a game in the top lane, I'm ahead in cs by 20+, then enemy jungler comes in for the gank. Doesn't score a kill but takes my flash and requires me to B. But when I use teleport to come back to lane my lane opponent now has 2 levels above me even though only having enough time to close the cs gap to me still ahead by 10. How does that work?
