TFT Tier 2 & 3 Droprates increased
Tier 2 and 3 champion drop rates have been adjusted. In short, the Tier 2 and 3 champions are now more likely to appear. Previously, Tier 2 champions would only start appearing after Lvl 3. and Tier 3 after Lvl 4.
Both now have a a smoother drop rate percentage curve as you level up. It's easier to fit those Tier 2 and 3 champions into your strategy and utilize them now.
However there's a catch. Tier 4 champions now have slightly smaller chance of dropping at Lvl 5. and Tier 1 units' drop off is far steeper now.
