Did you notice how your w turns green now? Once you get the feel of where w is naturally, use it to your advantage.
So if you pop w while in the middle of a protobelt dash, you and everyone who saw the dash on thier screen will not see your w, inclu d ing yourself.
Sonce Riot won't fix it or rework morde, ya run exaust and ignite and go Conq or Aerey. Conq is OP because it's bugged with old coding on w and does double damage on w overlap like he was first teworked, but only when Conq is active and it's cast on an ally (adc Mord).
You time your w popping proto leap in a teamfight come mid game, exaust them, ignite and ult the lowest hp squishy, activate q, e and AA away, watch w being geen to know when its up, and they will die without seeing it, and your reward is free multi kills ;)
Riot doesn't want to fix or rework Morde, so let's make the most of the bugs and a broken kit, huh?
