Here's some strange interactions that occur when teleporting allies with Dynamo's 2 that seem unintended:
Dynamo can grab allies through Kelvin's ult.
Ex:
If Dynamo is inside with Kelvin, and allies are close enough to the Kelvin's Barrier, Dynamo's teleport will grab the outside allies and bring them inside.
If Dynamo is outside Kelvin's Barrier, he can bring Kelvin or any other allies trapped inside to the outside.
Also,
Shiv's Damage Deferred gets cleared by Dynamo's teleport (same effect as Shiv casting his 3 on himself)
