Are you doing this with a static group? Any members that have gotten a clear before? My FC still does it the 2 tank way with the members we are trying to help usually going in as dps and we get 4 meteors max with 4 dps (sometimes 2 of them are the ones being helped). We stick to 2 tanks to guarantee no funny business is going to happen during golems phase even with our fc's only coil group (3 meteors with 4 dps before echo).

Anyway, if no one in the group can parse, your best bet is to rely on the party's enmity list and look at your ranking on there. There's quelling strikes but I don't think it is absolutely necessary on phase 1 as long as the tank can open the fight well, so you can try that for a handful attempts just to see where you are in the party.
