Giving Shen "stamina" restriction on teleport summoner
I was thinking since the main reason shen is ignored so much is because he can be too good at split pushing. How about if he uses his ultimate the teleport summoner gets a range restriction that increases over time. by 25 seconds or so it has a range of about the range of pantheon's ult. and by 45 seconds pretty much the whole map is available. Over that much time I could almost walk to wherever I want to go.
It makes sense too since he just channeled a lot of energy to travel across the map he's exhausted from jet lag.
