nub question

He like a lot of other champions is a situational pick. I think one of the main things that sets him back is the strength of tanks and generally AD heavy team comps. Tanks do a really good job at peeling and are generally tanky enough where ignoring the rest of your team for several seconds has no impact on their health bar. ADCs have BT and sometimes GA which do a really good job at keeping them alive, plus you have the 1000 shields that supports can offer today and redemption heals. Then if we consider how much of a range Zed usually has to close he will most likely have to use W which takes away a lot of burst and leaves him vulnerable after getting on his target. If we are talking mages too though, we have Zhonya's which completely fucks Zed. So as long as we have tanks in the meta, strong supports, and AD heavy teams we probably won't see Zed rising in strength or even being strong enough to be consistently picked.
