Was thinking to myself of a new way to look at elemental spirits usefulness. I'd like to introduce a new concept called "elemental Purge" or "surge"? This new job ability would SHARE timers with "elemental siphon". This new /JA would rather than return MP to a summoner, instead cause a violent explosion of the spirit(treat as a tier III or IV).
While not much, since timer is 5min, I can see a quick use reason in-between blood pacts and blood wards. This also would eliminate the useless waiting for an elemental spirit to cast an AM.
All the standard rules of elemental damage will apply such as weather an mob resistances.
