Ryze ulti isn't a teleport, but a relocate
What i mean is that his ulti isn't used like the other teleportation ultimates (
) those ulti are used to gank, but ryze can't gank with his ulti
his ulti shows up where he is going, the range is very short, it's a nidalee spear at lvl 1 and 3000 range at lvl 2. But since it takes 2 sec to channel, at lvl 6 if he wants to gank somewhere walking will be as fast as ultying.
but his ulti has an other strength, not only he teleports his allies, but he can do it in fight unlike tahm kench, he can use it to teleport assassins into the backline but also it means that ryze will be a hard counter to A LOT of champs
ultied an ally? relocate the ally out of j4 ulti.
hit an ally with an arrow? quick save him by ultying before the enemies arrive.
and it's the same against

so please, stop saying that ryze's ulti is similar to them.
