A lot of you don't understand why the queue sistem as been removed : ifrit.
Since it's impossible for them an this time remove the animation lock, queuing magic would be 100% death in this fight. Basicly, if you're casting something, have an eruption below you, the animation lock you in place resulting in severe damage.
