In the team builder and server, have the option to connect to a database that will give you the bans, restrictions and challenge options for literally any tier you can think of. Also, have the option to download the settings of a tier (and tier category) in the team builder, with the ability to delete any of them. Default categories could include PO's main 6th/7th gen tier list, old gen ou tiers and fun tiers. For instance, as a gen 1 battler mainly, I could care less about a lot of new gen tiers, but I might want to explore different gen 1 tiers like: stadium, tradebacks, mewbers, rby monotype etc. Another group of people might want to do this in gen 2 or 3. Each entry's settings could be approved in a thread. In other words, solve the problem of having too many tiers that you don't care about, whilst longing for tiers that aren't there.
