Interesting note about spirits

From summon (assuming you have hate on a mob so don't have to use assault) a spirit only takes 11 seconds to cast a nuke, following this it depends on your summoning skill (capping at 25 seconds). What I found interesting is that unlike blood pact timers, this casting timer doesn't carry over to the next pet. So it's actually faster for a solo smn to summon a spirit let it nuke release it and resummon it than it is to keep the same spirit out and let the timer go down.

Not sure if this has been said before or if its already widely known, but I found it an interesting bit of info and thought I'd share.

I took into account using assault immidiatley after the spirit begins casting and the only time this was faster than resummoning was in the case of an Ancient magic.

Assault during T4: next spell cast in 22 seconds
Assault during AM: next spell cast in 13 seconds
Resummon after casting a spell: next spell cast in 16 seconds

resummon is including the time it takes to release and resummon a spirit.
Ancient magic was faster by 3 seconds. So if your spirit casts anything other than an AM it will cast faster if you resummon it

yep, spirits have behaved this way for years
