Cho'Gal: Because I wanna see how bad Duo's can be, and how he would fair in the LCS
Loki: Because Assassins were never bad enough.
Tychus Finnly: Because I want to see him and Graves be Vape Bro's
Just three Chens from HotS, because he's so fun and I love his brew mechanic. ...Two Chens and a Khazarim, since he's a support that can actually hold his own AND has dashes, and we've desperately needed a support ticking those boxes for years.
Samuro: Because stealthy bladestorm!
Freya: Because we need an actual AA mage
Phantom Assassin: Because that 450% crit would be hilarious with IE
Rubick: Cuz crazy ultimate copies and stuff
I have 1.3k hours in Dota and the three I miss most are: Slark Slark Slark
Note: Mainly from Heroes of the Storm
Slyvanas Windrunner: Because she's one of the best seige heroes in the entire game with the ability to DISABLE structures and minions.
Abathur: Because a hero that doesn't have to be in the fight to do some fighting. AKA a symbiote.
Sadly I can't think of another. Maybe Cho'Gall?
