Riot did a pretty good job of trying to make Morde a bot lane mage - Why isn't he picked more bot?
So on paper morde bot is really good. He does have clear weaknesses but clear strengths too.
The XP passive on his W allows him to have a level advantage, w movespeed and heal is really good for bot lane for both him and his supp, having range on E allows him to farm without meleeing all minions and poke and zone a little too. His base damages without items are really good, he can turn a 2v3 around by killing the adc with ult, he can push bot really hard if he kills enemy adc with ult, dragon is right there and if he takes it he can have some serious pushing and skirmish power for a little while, and he can start targon for additional gold for his sp and sustain in addition to w sustain. He can also build so many ways - straight ap, hybrid, or AD.
His biggest problem is landing triple q when the enemy supp will have cc and all the mobility on marksmen these days. But with probelt and a good supp with CC its not impossible.
Why hasn't this move from Riot been successful?
