TELEPORT TAKES TOO LONG!!!
As i am writing right now i am playing a game in league. I have considered of picking Teleport as my summoner name for as it is very essential for a declaration of a team fight or a start of a team fight. As i first noticed it in the patch notes. 4.5 seconds is not as bad as it looks like but in game. It seems like it takes forever to channel. If you would teleport into a team fight. Team mates would already be dead and you're there left to be killed. If you would teleport to initiate a fight, enemy team is already far away from your reach. In conclusion, i think it is stupid for teleport to be nerfed into a 4.5 second channel without any buffs or balance into it. You have just made the summoner spell to be weaker in its purpose.
