Can someone please tell me where the hell "support" Zac came from?

I just lost a game because a "support" Zac would decimate our entire team from a single combo. He, and their Skarner jungler, made me (Caitlyn) completely useless. One E-W from Zac was enough to shred half my health, and then couple it with infinite stun from Skarner............my support Bard had as much gold as me, and I finished the game at level 16.......the lowest level in the game.....

But this isn't the first time, either......I've probably faced 3 "support" Zacs by now, all of which outscale their own ADC, and proceed to rip teams apart single handedly! Without them, their teams can't even win a 4v3! But bring in Zac, and he'll solo 3 of your squishies easily.

This is kind of reminding me of Top Lane Tahm Kench..........impossible to kill, while also doing a fricken crap ton of damage, while being able to come out from seemingly nowhere!

Seriously....where and when did this crap start, and how the hell do you counter it in the bot lane?
