TP balancing idea - TP denial

TP have been so overused especially by Pro players.

However I don't think nerfing TP would be a great idea. Simply because it provides more impact for hard carrying mid or top laners. Base from my experience, it is like a race on who could TP in first.

1st balancing idea:P Denial 1 TP Denial, like TP targeted on wards/minions does not make it invulnerable, just additional hit HP.

2nd balancing idea: TP Denial 2 Enemy can target the targeted TP to deny the TP and overwrite the TP. That will be so much beneficial for the later champ to TP but will be so late for the fight that he would better cancel it instead.

Thinking of this TP denial thing is fun for me actually. Having a tool to deny the TP gives more option than adding another champ somewhere. And we champs like thresh and Jarvan already have something 'can't be attacked' to be used for TP.

What do you guys think?
