This should include Guardian/Destruction Stones & Life/Harmony Leapstones. This should also include Life/Harmony Shards as a currency, make them accumulate for the roster, like Silver, Gold, Pirate Coins, etc.
That way it doesn’t matter which character does a T1/T2 focused event, it’ll apply to the roster.
It solves all issues for people with T1/T2 characters, and helps them catch up to T3.
It doesn’t tamper with T3 progression.
Kind regards.
