So i have thought about a few improvements we can give the game
Nr 1 I would like to see realm migration be a thing again so players can move freely to new realms and populate them
Nr 2 Add Surnames/last names to characters so player identity is kept. This can help keep the uniqeness of a character for a player but opens the chanse for realms to be shut down so we dont have so many low pop realms who need to be sharded over to other realms to even seem populated
Nr3 I would like Sharding to be removed because it is messy. Nothing feels worse than Seeing the levers and then starting a group. You then head to the area where the rare spawns you see it emerge and then POOF it is gone cus you sudently sharded over to a new realm, This has happend so many times now. Thats including world bosses and other rares so please remove Sharding
Nr 4 improve on the Vault for delves Blizz does not Punish Billy by making his +10 mean nothing because he choose to do timewalking. so that a Delve which is cleared at tier 8 does not matter because you choose to light the lights in Hallowfall on the way to a new delve is just stupid. So make it that the highest effort you made is what counts and not the lowest on the Vault counter
These are my sugestions and other sugestions are welcome aswell. We all just want a fun and rewarding game after all
