playing a match sometime ago was up against a ziggs things were going well till top lane jarvan came to my lane and double teamed me with ziggs I was thinking I could handle but little did I realize that miasma is not doing what it is supposed to do....shortly after that jarvan got in close ulted and chained ziggs ult and I lost the lane for about 5 min due too a double mid.

morris15 votesJarvan dash ignores all crowd control if he's able to cast Q on a flag. It isn't a movement spell in the traditional sense and even the tooltips mentions it.
Nahui2 votesJarvan's isn't a mobility spell technically. It just causes mobility. Grounding doesn't prevent mobility, just prevents mobility spells from being cast or you'd have champs like LB cast W and have it go on CD and use mana, but not go anywhere. With this in mind, we look at Jarvan's pull. Miasma can't stop the flag cast because it isn't mobility. It can't prevent Q being cast because Q is simply a linear skillshot. But, the coding has Jarvan pulled to the flag if the linear skillshot's hitbox hits the flag's hitbox. So, it evades Miasma because it wasn't a mobility spell, just an interaction. I'm fairly certain Ziggs is the same with his satchel charge.
Miasma should stop Jarvan from ulting because that is a mobiility spell. But only from it being cast, not mid ult. The pull I believe is entirely exempt though since there is no mobility to be cast.
Automated Riven1 votesYou can't cast mobility spells while grounded. If lb is in miasma then she won't even be able to cast w. There is no casting and losing mana and not going anywhere.
Nahui1 votesIf you read my comment, you'd know I didn't say that at all.
Automated Riven1 votesoh my bad. My brain autocorrected your post. lol
Nahui1 votesHaha I figured.
Automated Riven1 votesI downvoted myself for justice.
Nahui1 votesI'll upvote you to counter it, no justice needed.
Colgate Gator1 votesIt sounds like he passed through the miasma mid-dash, and I'm not exactly sure if that spell stops ongoing dashes, I don't see Cass enough to see that.
ForFoxSakes1 votesIt's like people taking thresh lanterns - it hauls the champ away rather than the champ doing a dash move
PopcornBunni1 votesIs 
's spear toss not a mobility spell by the same game-logic?
I've never seen those two against each other to know.
