Yes I'm not even much of a kicker, but I wholeheartedly agree that this kick in particular is underpowered, ESPECIALLY when used by itself.
Trust me last thing I want is this to be OP lol BUT if a strong kicker catches you at the end of a crisp teep or front kick, it should hurt. I guess that means more stopping power please
Yh the teep kick is very underpowered and should at the very least cause a tiny bit of hit stun when used from the right range. The vid in the link I post below shows perfect example of how it should be when landed cleanly from correct range. If that same little bit of hit stun you see happening to Mcgregor happened everytime you landed a clean teep kick from the right range, the move would all of a sudden become useful by itself. And it's nothing overpowering that sends my opponent sailing across the octagon or allows me follow up strikes, but just a short little bit of hit stun that doesn't allow the opponent to fire back before you can at least get your guard up.
