He still ain't wrong though in general.

You can even take 2 BLM instead of 2 ast and have 6 flare/freeze charges of 2*12k st + 8k aoe, 4 * 3stack superflare dot/stun and 2 fouls for 16k dmg, and their lb recharges almost twice as fast so if you have 2 drk's you can do it again every minute if both drk's rotate.

Great to have an ast in your raid, but 2 ast really isn't the top combo for drk, there are several other ones that are straight up better.
