In today's PBE Update, featuring this year's Harrowing Skins & the K/DA Skins (So far, my favorites between the two lines are K/DA Evelynn & Count Kledula), we have nerfs aimed at the Time Warp Tonic.
Time Warp Tonic:
- [New Effect] "Consuming a potion or biscuit grants 40 of its health (and 25 mana if applicable) immediately, with the remaining amount delivered over the usual duration. In addition, you gain 5% Movement Speed while under their effects."
As RIOT Rovient said, this was done to "reduce lane sustain of corrupting potion & Timewarp Tonic". Now this will no doubt hit Lane Sustain quite hard, but I feel like this will make it so no one will use the Rune at all. Sure it still gives the 5% Movespeed, but I don't see alot of people using this version of the rune.
