Blinded me with Science! (or number crunching)

(click to see enlarged - green rows are currently equipped)

So I'm slowly gathering more Frosties to bump up my gear. As of now, I've got the 4 piece Tier 9 (Conqueror Turaylon's Battlegear) and I have one piece of T10, the shoulders (part of the Lightsworn Battlegear)

I never got the T9 shoulders, so when I had enough frost emblems, the shoulders were the obvious choice.

(note, my first Frost purchase was the Might of the Ocean Serpent cloak. My previous one was SO bad that it, along with its gem slot, gave me a MASSIVE upgrade, more than the others)

So now, I am getting to where I will have enough to buy a second piece of T10, and I am considering what the proper order of the upgrades should be:

- Which item should I buy first?
- Is the 2 pc T10 an upgrade to the 4pc T9?

Well, if you look at the top of the page (and click the picture) you can see my handy dandy little spreadsheet comparing all the items and describing the relevant 2pc and 4pc set bonuses.

The first and biggest thing I notice is the difference between the chest pieces: I go from having Armor Penetration (ArPen) to Haste. (with a bump in numbers overall as well) I seem to recall haste is pretty good, but can't for the life of me recall how useful ArPen is.I sat around googling, until I went to the usual place (EJ HERE) and saw that haste is unequivocally better.

Now, the bigger question is if the 2 pc T10 bonus (40% chance to reset timer for Divine Storm) is a bigger benefit than the 4 pc T9 bonus (additional 5% chance to crit with Judgements)

On a gut level, the 4 pc T9 bonus would be better for single targets, since divine storm is only really good for multiple mobs. BUT, the speedier DS, along with the other stat increases makes me wonder.

And in case you're wondering, I haven't used RAWR in a while, because Character Profiler has been giving me troubles, and manually upgrading stuff in Rawr gives me a headache.

I still need to get some better trinkets and librams, but I really despise "on use" items, which most of them seem to be. Eh, maybe I should just go with the Herkumel War Token. :P
