Stealth/Undocumented Malzahar Nerf (Bug?)

In patch 6.7 the vision changes nerfed Jungle Malzahar pretty hard. Specifically, Malzahar's Q now only grants vision of the area directly in the hitbox of his spell -- or, in other words, nearly no vision at all. Previously, it granted extended vision -- similar to how Caitlyn's old trap vision worked.

For **mid **Malzahar, this is only a small nerf -- you can no longer use his Q to periodically scan for incoming ganks. For **jungle **Malzahar, however, this nerf is pretty bad -- the vision granted by Malzahar's Q allows you to scout for jungler invades, something that Malzahar is already incredibly susceptible to in the early game. Without this vision, Malzahar no longer has any tools to combat a Lee or Nidalee in the early game.

My question about this was, seeing that this wasn't listed in the patch notes, was this an intended change? Can any Reds comment on this?

p.s. As a 1 trick Plat Jungle Malza main, if anyone wants to talk jungle Malza I'd love to answer questions :P
