I tend to jump earlier in combat anyways and the animation in jump is touch shorter. I don't think this is going to be as much of an issue.

However, in that particular case I'd rather clip the cooldown on Jump, then clip the combo and risk losing BtoD prematurely.

Rotationally this shouldn't affect us too heavily as we're best positioned on the "Corner" and adjustments for context should be fairly quick - baring specific fight mechanics. Given the line-AoE nature of Geirskogul, that will actually give us some range on its use as well.

Anyways, jumping into the conversation of simplifying the guidelines into an easy to understand priority system - just off the math theory we have thanks to Thendiel - it looks like the "Green Light" for using Geirskogul is if your BotD timer has 19 or more seconds left on its duration, or if your BtoD timer is back up/nearly up.

Everything else seems fairly straight forward giving a matter of discretion for usage of Life Surge. Seems to be a matter of using it for 4th Tiers or True Thrust, whichever is the closest cooldown when LS returns.

As far as controller usage - I have a fair amount of redundancy on my controls anyways (I hybrid my defensive cooldowns). I'm fairly certain I can arrange some of the "4th" attacks to still feel comfortable in my setup.
