This would add skill to hero selection and gameplay both, as well as (I hesitate to say it) reduce frustration, pain, and wasted time for players.
They could even make it optional behind a button so people wouldn’t have to use the tool. It would just be something like:
First 100 Tiles
Red - 20
Blue - 20
Green - 20
Purple - 20
Yellow - 20
It would add skill to hero selection, allow for a greater variety of heroes to be used, and eliminate RNG complaints on the tile side of things. Easy, ethical, and transparent.
