ACN rotation help

[Kevee]

I may be a bit ignorant here, but short of Ruin II costing more mana... why would you choose ruin I over ruin II; short of you running out of mana?

SMN has major mana problems if you want to keep up Thunder, and at 50 Shadow Flare, while maintaining Fester use and never using Energy Drain.


A BRD does rectify this, but SMN has pretty big mana problems for the optimal rotation.


Basically, it boils down to this:
If you have time to use Ruin or Ruin II, use Ruin II only when you need to use an off-GCD skill.


Edit: This is about the ~4-5min mark that you'll start to run low without a BRD. If you ever need to re-summon your pet or battle rez, this problem is greatly exacerbated.
