So I hate Agressive Refrain

why not?

My attribute spread is 14 spear (with a sup rune), 11 command (can be lowered to 9 if higher command is not necessary, thus raising spear to 15), 12 leadership. I also have a sup leadership headpiece for casting AR.

I thought the common consensus nowadays in PvE is to use Sup runes? Well seeing as how I'm a two month old player I assumed more HP was better?

Maths check.
In naive theory, Flurry is a 33% IAS and if maintained will result in 50% more hits in a given time interval.
Each of these hits only deals 75% of the normal damage.
1.5×0.75 = 1.125 - a 12.5% increase in average damage.
Since it's impossible to perfectly maintain Flurry without a recharge reduction modifier or something to enhance the duration, but it seems unlikely that Flurry will drop below being a 30% IAS assuming you have the energy (hitting a skill on recharge isn't hard, the main limiting factor is ping) - 7% increase in damage from autos.
Note: Flurry acts as a ~30% IAS if you activate it every 6 seconds.

Aggressive Refrain (and indeed any 25% IAS) results in 33% more hits in a given time interval.

When you start adding in adrenaline and damage boosts, Flurry does better simply because the damage reduction doesn't affect bonus damage (from skills or buffs) and the extra hits give more adrenaline (more damage skills or shout spamming).
That said, Flurry is bad because it takes up 3 pips of energy regen to keep up. Frenzy only takes two (a little less) but Aggressive Refrain is the most energy efficient (as well as being the most convenient and having a negligible downside).




Refer to the calculations above.
Looking at that, you have your IAS calculations wrong.
An X% IAS works by reducing the attack interval (time between hits) by X%
So a 33% IAS reduces the time between attacks by 33% which in effect (say 33% = 1/3) results in 50% more attacks (1 - 1/3 = 2/3 "time/attack multiplier" leads to a 3/2 "attacks per second multiplier").
So assuming perfect uptime on Flurry, the difference between it and AR (or indeed any 33% vs 25% IAS) is actually ~17% (1.5-1.33) more hits. If you treat Flurry as a 30% IAS you're looking at ~10% more hits. Whoops, don't know how I messed up my first one. However, I think I'm still right on the second. You calculate it simply by dividing the relative attack lengths as .75%/.66% = 13.6% change from 25%->33%.

You calculate it simply by dividing the relative attack lengths as .75%/.66% = 13.6% change from 25%->33%. I made a mistake in not relating to the 25% IAS (I related to the base attack speed).
Also, note our exact percentages vary because I'm using 1/3, etc. over 33%, et , resulting in neater numbers (12.5% exact over ~13.6%).

Well seeing as how I'm a two month old player I assumed more HP was better? Depends really but for the most part, for any offensive class (aka, everyone exept healers), it is better to use a sup rune in PvE, assuming you have your superior vigor rune as well. PvP is different, however.

More HP in general is bad because it requires you to sacrifice runes that could be going towards defense (Sentinels, Blessed, Centurions, Tormentor's, Minion Master's etc.) Additional defense is usually superior to additional health. I know, I have two sets on my Ritualist, one for PvE SoS with full Shaman's insigs, and one for PvP with full survivors. Of course, I use a Major Vigor rune (no superior yet, too poor). However I'm still wary of sacrificing hp by using superior attribute runes, for any job.

pro tip

Don't waste the skill slot - use rock candy or pumpkin pie for IAS. Blowing money on cons everytime you want an IAS is rather stupid.

pro tip

Don't waste the skill slot - use rock candy or pumpkin pie for IAS. That is one really idiotic tip to be honest. So you should waste money on things to use them in every area?

pro tip

Don't waste the skill slot - use rock candy or pumpkin pie for IAS. A pretty expensive solution, expessially for every day/nm business. But the tip is to remember, if you can farm some or feel like buying a couple of those. SHould you need an extra skill slot or 2, you IAS can be replaced with those.¸
But the point's moot in nm and with a fully built 7-hero team, I heard every thing can be done easily.
