My druid fire / cold aura (generally using the fire one) seems to be dispelled or disappear often, even after just putting it up. I probably just missed the discussion, but what is over writing these? Pretty sure its chanter or bard related, but can't say for sure.
The Enc nuke aura (Mana Reverberation Aura) overwrites because it's better. Well, kind of. The buff each aura casts is 18s duration and will overwrite any existing conflicting buff. So unless the cast times are sync'd, the group will get 6s of one, then 12s of the other. Which does come in handy when burning because twincasting each up the charge counters much faster than 18s. So keeping both up can provide more damage to a group using twincast effects.
