Yeah for us Chiralda usually goes down pretty easily but our BRDs just can't deal with Suprana and they die to her too often. Hence why we're going to try dropping a BLM and a BRD.

From our many many runs so far we've found that you only really need 2 BRDs to deal with plumes up until her last set of them before Aerial Blast where she spawns a shit load of them. For that one we'll have the DRGs help out with Keen Flurry > Ring of Talons x2. DRG also has Dragonfire Dive which is a nice quick way to help out the BLMs if they're struggling with Chiralda.
