Welcome Enlightened,
This patch features a whole host of systems changes directed at breaking up the meta. The way to play TFT over the past few patches has become too rigid. In particular, key Tier 4 champions are making a splash too early in the game, leaving very little breathing room for Tier 2 or 3 champions to shine. These changes should open up opportunities for different strategies rather than just rolling down at Level 7 to build an endgame composition. We're looking to do this by pushing Tier 4 champion and chosen roll odds back to Level 8.
Be sure to check out the changes to Warwick, Jinx, Lulu, and Yone. They've received significant adjustments that may change how you use them going forward.
