Can't speak about raiding but DRG is very fun to play. We have so many oGCDs thanks to Mirage Dive, we're always weaving stuff.
I think the following changes would make DRG competitive but not overpowered.
-Let DFD grant Dive Ready (it's a 3min recast, so why not!? It would help with opener getting to LoTD in 30 sec instead of 70)
-Lower Mirage Dive animation lock (sorely needed)
-Let eyes be maintained even after BoTD falls off (essential for invuln phases) or at least lower recast of BoTD to 20 sec so we can use it to maintain the buff to keep eyes since losing all eyes costs us 90 seconds until we get LoTD back up.
-Lower Geirskogul recast from 35 seconds to 20 seconds.
