I know maybe here is not the place to post, but I have a very great idea with the game, so Hots havent the ice spells in the real in the heros, what if Summon Sindragosa the ice can slide, and make the same with other heros so, the allies of the team can just go fast in the ice and slide, that will be awesome, just like Blaze with the oil, just instead of slow, is a boost of walking, I hope you listen to me I think is a Great Idea for the game.
Increasing movement speed AND slowing (or rooting) enemies in a VERY long line? While it does seem cool (pun intended) I highly doubt it would happen.
