The new Q is an awesome ability when two targets are are present, he seems to be very good in botlane 2v2/3s IMO.
Since the ultimate is very utility focused, it can be amazing for getting people off of your ADC or moving a gank squad under your tower.
Anyone given it a spin? What do you think?
I Played a game or two of it, your cool downs are so long in lane I don't see it being very good, although this account has no CDR runes so I could be wrong. Zac gets a lot out of levels because all of his cool downs go down and I think thats gonna keep him from going support.
Also Zac sucks as a whole right now, even for his intended role.
Really the problem I see is that 2 of your 3 moves aren't going to be used too often unless you are going to hardcore dedicate yourself to going all in the moment you hit lvl 2~3.
Like, if you have someone that is really strong with that 
I can see getting a lot of mileage, kind of like a more risky, higher dmg Leona.
Personally I just prefer using is E as a tool to gank at weird angles so I prefer to play him in the jungle.
