AP top laners
I was wondering, except the usual ap top laners:
+the guys that build quite tanky, but still do decent magic damage:


Some ap top champions bring utility, good cc, or aoe damage, others good wave clear and so on...some have escapes, some are immobile, so there is no special condition for playing a mage on top from what I see.
So when people picks
,
,
or even
on mid, why dont we see champions like
,
,
or
on top lane?
