ARAM Zilean Needs an Ult Nerf

I just played against this, and with the standard mana items, full 40% cd (with the extra 5% and if he takes the ult cd rune), he can ult every 30 seconds or so. In poke oriented gameplay like ARAM, he can essentially ult twice in one teamfight, which is complete bullshit in that mode. In SR, you can reset and go do other things, but in ARAM you are consistently punished against this guy. There is no counter play to free GAs for multiple members. If the standard GA was removed from ARAM (even though they could have just limited the item to certain champs or made the CD ridiculous as a trade off), then at the very least Zilean's max 3 ult should have a cd cap. It's not the same thing as a Lux for example ulting every 30 seconds, since that's dodgeable damage. Zilean ult is one of the most impactful and forgiving mechanics in the game and in ARAM it completely breaks the game with the proper build and runes.

To prove my point further, ARAM's whole purpose is that you are forced to fight with no basing or healing. At a certain point Zilean can hit a point where mana is literally 0 issue, then ult himself into turret to revive with full health. The multiple healing fountains and runes/items are more than enough to refill his mana bar, so it's as if he is getting a 2 second reset every 30 seconds if he feels like it. Not to mention the four other players he can do this for.

I know a whole bunch of tweaks were just announced on the PBE for ARAM, but I did not see Zilean on there. Hopefully it's something to consider.
