Teamfight Tactics new champions and the shop.
I really dont mind adding new champions to the game. I think it keeps things interesting. But as RIOT adds more champions it becomes harder to lvl champions up. I have lost multiple games lately with only 1 or 2 lvl 2 champions. This is a really easy fix. For every 6 new champions added to TFT add one more shop slot. So instead of only having 5 choices you have 6. This will keep the game moving at the same pace it was before and give people the opportunity to actually get the champions they are looking for.
