In a post on the official RIFT forums, Pithos (a developer for the game) gave a little insight about what may be coming down the pipe for PvP dimensions. While he couldn’t pinpoint a release date, he said that work IS being done in this area, and he hopes it is what fans are hoping for.
I’m the one that has been working on PvP Dimensions when time allows (which has been rare!)… There’s still no official release date set – it largely depends on how many features we want to launch with, and how often other tasks take priority. I’ve got a very basic version fully functional now. Current working example: Click a banner to join a team, get teleported to your team’s start point, fight, get a point (or points) each time you kill someone on a different team, when you die and hit respawn, get teleported to your team’s graveyard and resurrect, and then at the end, declare victory for the winning team (or a tie!)… All of this within a dimension of your own creation, of course. I’ll be talking with Daglar some time soon regarding when & how we want to release this.
While it doesn’t sound like these features will be coming anytime soon, fans can rest assured this appears to be a priority for Trion. You can check out the RIFT forums for the full thread, and be sure to leave your thoughts on what should be included in PvP dimensions in the comments below.
