A small lux suggestion
Lux is one of the strongest champions of TFT and as a player i usually want to have her in my comp. But she is rare by herself, and more than that, she has types. So, in the current version getting a 'proper' lux is a matter of luck and nothing more.
This set was announced as 'Master of elements' season, encouraging players to adapt for different arenas. So, lux can be made more predictable, if each type of arena will contain definitely 2 types of lux. For example: Ocean arena: glacial/ocean lux Mountain arena: light/woodland lux Infernal arena: inferno/shadow lux Cloud arena: electric/cloud lux
This would make all the lux matters easier to calculate and thus. more comfortable for players.
