So have guilds started transferring to ollo or is that still a few weeks away?

According to Celestrata, Trions Community Manager for Archeage, only 0.8% of active characters across all evolution servers have elected to transfer so far. Looks like the active players are choosing to be evolved.

Pretty small fraction of players.

Or Trino are counting every toon created (all the free account toons) that no one has been active on for a while and the reality is that the metrics they are spitting out are intended to support the idea that how they are doing server mergers is what the community wanted.

My money is on weighted metrics to support a message.
