Thanks for pointing these out! I made some improvements to the randomize button so it should work better (ex. PRX should only go in slots 1-2, T1 only in slots 3-4).

The randomize was just an extra feature added to mess around and doesn't factor in all the possible scenarios.. If you use the dropdowns to select a team it should have a realistic view of the teams that can fill each slot

I updated it so the share button now generates the group/playoff bracket for any new links generated

Yea you're right the share button only shares the initial teams, not the groups/brackets cause they are randomly drawn anyway. I added a comment in the OP (if enough ppl want to share those pickems I can make the changes to share that as well)

only if I can pinch yours

Nice catch thanks! I added some extra logic to prevent that from happening - it should now behave as when they do live draws (I can see why they can be so complicated sometimes)

It's just a simple tool where you can pick teams for each region's seeds and then simulate the possible brackets for Champs. The teams for each slot are highlighted whether they are eligible or not and you can randomize the seeding for groups stage as that will be determined randomly through a draw by Riot.

I'm working on some other stuff like the possible scenarios for each team to qualify. If you find any issue or have suggestions please let me know :)

The share button should now generate all sections include the group /playoff brackets.
