Personally, my interest in the game was battlegrounds and I choose to leave because of the removal of /follow.

You can attempt to work around the removal, via:
- Multi-person mount... box that many toons.
- Use IWT once you're in range of whatever, if you're a melee team.
- If you have a Druid on the team, with a Minor Glyph your travel form is a mountable 'Stag' which your team can IWT with, so they'll run to the lead toon (assuming you lead with the Druid and are okay with being in travel form almost constantly).



Rift recently removed follow from their battlegrounds (warfronts, or whatever).
But Rift is Free-to-Play.
Everquest I, Everquest II, and Vanguard are all Free-to-Play; there isn't anything like battlegrounds in these games though.

Personally, I'd pay for the pvp if it was available.
But the PvE isn't really all that interesting to me... Free-to-Play, is an option for PvE if you don't want to give Blizzard money.
