The introduction of new characters to TFT and the problems thereafter.

A great game mode, by every standard. I haven't really played any regular League since TFT came out. However, with each patch, comes a new broken champion which is automatically enabled in ranked mode. 9.16 is a prime example of a broken update where all anyone really needs to do to win, is get Jinx to silver. 9.15b, it was still a Cho'gath/Karthus game for the most part.

If anything can be taken from this, enable these new characters in normal TFT during the primary patch, and when the b-side is flipped enable them in ranked once everything has been balanced with the otherwise imbalanced champions.

I love TFT, but when events like these occur it makes the game mode inflexible team-wise, and virtually unplayable as everyone will be aiming for the same team comp almost every time.
