The current tag system requires a loading screen to switch between tagged characters, thos killing the imersiveness of the game experience.

Suggestion:

-Alternative #1: The tag system could be using the same basis of the current transformation method, like the "Mischievous Jack Transformation Scroll", summons the model to the map, then allow the interaction by pressing the key "R".

-Alternative #2: Another possible transition method could be, the same method we use to enter "Elvia Realm". In this manner, the switch could require a progress bar that can be interrupted willingly or by events and other players.

Having a real tag system that remove the requirement of loading screen would improove the gameplay experience, and even allow future new content that could use the tag system in game, for things like PVP, PVE, Quest, and a lot more.

1 free tag a month, if you want to tag you have to wait until the next month or pay to tag.  People that constantly retag would be paying silver, but someone who might change very rarely would be able to try out a new class without worrying about spending 3b silver to do so.
