teleport absolutely must change in s6 . and cooldown is not the answer

cross map TP plays were cool fresh and exciting for a while riot . but now its not that interesting anymore watching every game be "oh fight botlane. oh 2 teleports yadda yadda" pro play is getting stale from this i think teleport can stay however . with a tweak this might make it better for the game and not feel as mandatory / played out

1. teleport has a range about equal to pantheon lvl2 ultimate . can be targeted on ground without a ward . has 5 second channel time . any damage taken ends the spell
2. the entire enemy team sees a clear visual on the minimap when enemy is using teleport . this visual starts at the start giving enemy team a full 5 second warning . the visual is a swirl with the champions face so you know which champion is using teleport and where he is teleporting to
3. after teleporting your champ gets 25% increased movement speed for 20 seconds . this ends when you take damage from a enemy champion
4. 4 minute cooldown . so its powerful but with drawbacks . no actual combat power so ignite will be stronger in lane with these changes . most midlaners would not be taking teleport, but tanks would be taking teleport for lategame flanks also barrier could maybe use some love to compete with ignite . my idea is give barrier a 60 second cooldown . make barrier heal for half of its remaining amount when it ends . but make ignite read "purges the enemies barrier on use and makes enemy unable to use barrier for 15 seconds" . this way barrier could be strong for trades in lane but ignite would still be powerful against it with a much longer cooldown
