Replacing Mirror

Hi!,

I'm developing web based Virtual world game like "Club Penguin".
I've been developed my game for 3 Months and its going very well, but lately I've been started to find that Mirror is less effective for my project.
For example switching scenes (Rooms), Its Impossible to switch scenes without switching to all the active Clients.


I thought about switch from Mirror to other service,
Currently I'm using PlayFab to store players data.

I thought about switching to Photon / SmartFoxServer...
