So the Nautilus changes
From the PBE:
Nautilus Titan's Wrath (W) damage while shielded decreased to 15/30/45/60/75 from 40/55/70/85/100 Riptide (E): Cooldown lowered to 6/5.5/5/4.5/4 from 10 at all ranks Mana cost lowered to 40/50/60/70/80 from 60/70/80/90/100 AP ratio lowered to .3 from .5 Slow duration lowered to 1.25 from 2 seconds
This might actually improve his jungling a little. The W damage is already useless enough in the first clear that being able to E twice as often might balance the W nerf. His ganks will be a lot stronger, since now you can get 2 E's off a lot of the time (especially if you save Q for when they flash). I like this, because a big part of why I used to play Naut jungle so much is that you can hold the laners in place for so long that your laner can follow up even if they made no attempt to set up the gank (and in soloq, you're lucky if they don't just keep farming half the time).
My issue is that these changes will actually murder Naut Support, which I main. You can't cheese people with your W anymore because it does so little damage at low levels, whereas before it was actually really good for trading. The reduced cooldown on E is useless because Naut isn't an all-in support, and he wants to wait for his Q/W to be up again to trade again regardless of the cooldown of E. E is even weaker because of the reduced slow duration.
If any Rioter sees this, please don't kill a perfectly healthy niche pick. If you want to buff jungle Naut, just have his shield take 50% reduced damage from monsters, and maybe buff the shield damage a little too.
Sincerely, a concerned Naut support main.
