I think varus could use this nerf if he needs any at all.

While im not really sure that his kit needs a nerf at all, id say to at the very least shift some extraneous power out of his kit which could be put somewhere else is to make his q slowly shrink down its range and damage after he puts it at max range, seems to me that varus has a massive amount of uptime on his zoning without much punishability, the way it works allows him at high cdr to basically hold a q all the way to the end and then prep another one .5 seconds later. I feel that if he needs a nerf it would just be to that so he cant zone forever and have 100% arrow uptime in his kit with some cdr, then they could shift some power elsewhere in his kit and maybe take the load of his power budget off his q a little since a lot of it is there for him and they could play up his other abilities just a little more.
