This is how we handle it;
-There are 3 inner circles, there are a total of 8 people on the raid.
-We split the raid inside the 3 circles prior to the meteor drops, meaning there's 3ppl in two circles and 2ppl in one circle.
-When you get the marker, you move out and place the meteor outside as usual->always be prepared to place 2 or more meteors though, so the spot next to you should be empty. If you get no second marker, just dribble back to your circle and keep an eye out where the meteors are being placed.
-In-between meteor drops healers do Medica and Succor, no problems there.

If you want more organization, you can place healers, dps and tanks in specific circles, but that shouldn't be necessary. Just make sure there's no more than 3 people in each circle. If one circle seems to be getting a lot of meteors, feel free to move to a side with less meteor drops. That shouldn't happen very often though, and it's not a problem as long as you see it coming.

Of course, there's multiple ways of dealing with the meteors, but we've found this by far the easiest and most reliable. The sprinting tactic is good as well, but it may be harder to manage due to latency and brain lag issues.

Good luck with your efforts, hope you guys clear T9 soon.
