When your have a perfect 5 man ult as MF..
But someone was drunk during planning.

When Jarvan ults and traps the entire enemy team...
Right before you hit them with your Sion ult...
Reactivate it early and you can jump his R. (Only for the most skilled and best ping Sion players out there)
It's possible. But when he ults literally milliseconds before you would have hit them...
Then thats just a dick move. He could have waited half a second more. Kill him.
Find me a bug that lets Sion kill his allies and I will.
I would if I could, but I don't even know how Tryndamere could kill his own allies.
Doesn't reactivation of Sion's ult nullify the knockup though?
If so, then what's the point?
to be fair you started ulting after I started ulting.
We'll meet halfway and say it was simultaneous.
i too turn into karthus.
When the allied Bard ults the Baron and you just flashed over the wall....
This also irritates me as someone who plays

I know that pain as an MF main :/ +1
When I play Zac, a Bard on my teamalways cockblocks me at some point with his ult. The anti synergy!!!!!!!!!!!!!!!
I can visibly feel the pain of my allies when I use a displacement ability in a game and immediately see my ally use an AoE where the enemy was. The anti-synergy is real :(
Poppy+Lee Sin sinergy. The amount of times I stunned someone into a wall, and made Lee miss his Q
I have long since lost count of how many skillshots I've accidentally made people miss with Force Staff or Venge's swap on DotA2. Though, one time was neat because I swapped right as Pudge threw his hook so the target was close to our team and I was immediately saved by Pudge.
Oh, and then there's the skillshots I've made accidentally made people miss while playing Kerrigan on Heroes of the Storm.
Ah... I don't stop feeling bad about accidentally making people miss skillshots until the match is over. Guilt is real.
Poppy+Lee Sinergy
FTFY
When bard hits no one except your team.
Wait, wouldn't the Bard R time out before Karthus R goes off?
If you pressed R at the same time, no. Karthus ult is a 3s channel, then damage. Bard ult has a 0.7s cast time, increased/decreased based off range, then puts champs in stasis for 2.5. So, in most cases, if Bard ulted at the exact same time as you did, your ult would run out before the stasis ends.
But you said landed, not Bard casts.
TFW When:
You're playing Fizz, need to Q through a minion/wave to escape death, and a teammate AoE kills all the minions before you can get there.
You're playing Bard and you make a portal to save your entire low HP team from certain death, only to magical journey 2ft into a wall.
You accidentally eat a minion next to a low HP teammate as Tahm Kench.
