Skarner on Twisted Treeline and alternate maps

So about this Skarner rework... Im an avid Twisted Treeline player (a little less now, due to the bot problem, but thats another topic) And i LOVE to play me some Skarner. But with this "juggernaut" rework... ive only seen mention of Skarner's crystal capture points on Summoner's Rift. Is there going to be a similar mechanic on the Twisted Treeline and even dominion maps? What about ARAM? Just seems kind of weird to have a map specific buff... i feel it leaves him in a worse position on the other maps if these changes aren't carried over there. I'm excited to see work being done on skarner.. but im not sure i love the direction its headed. Hmmm

Any word on that??
