haste vs ArPFollow

Just wondering whats best for a BE retri pala, haste rating or ArP?

Atm my gear is mainly focused on haste rating cuz I've always heard that's the best, but now I'm thinking on getting an ArP set - any1 know whats best? haste or ArP?

While I'm not Ret I did find myself curious on the answer to your question. Doing some looking into this I must admit I didn't find much. It looks as if Armor Penetration is not something to be ignored in the least, but that Haste seems to remain dominant when lined up side by side with Armor Pen.

The reason for this is because around 20-30% of Retadin damage is not physical, but magic damage. Because of this Armor Pen does less of an increase on DPS than it does for Rogue and Warriors.

Either way, it does effect ~75% of your damage positively, so it's not something to neglect if it's available to you.

Hope this helps.

You could try 2 pieces of gear with comparable stats on both with the difference being haste and one with Armor Pen. Then kill a few mobs, or do your dailies, with just a few pieces of gear and check your DPS differences using a separated-fight analyzing mod like Recap. It's hard as hell with high-end stats like haste/ArmPen, but just a thought. I hope someone with their own private server can put this question to rest.

Also curious as to why Warrior/Rogues get ArmPen but not Ret pally gear, for the most part.

both stats have benefits and limits.

haste is great for auto attack only, and affects proc rate from hits/crits. everything else is an instant(CS, WF, holy stuff).
ArP is great for all melee. worthless for your ~25% Holy dmg.

you need to base your gear on the type of fight and the enemy. if you're on an in-and-out or add-heavy boss, haste loses its luster. you can see a basic equivalency chart at maxdps.com

I'm using SoB since I'm BE pala ;)

Anyway, thanks again for all the answers :)
