So. I know you've been going on about how 2t10 is better than 4t9 and how adding 4t10 on top of that will blow t9 outta the water for Unholy.
Well, here's EJ's stat weight for all the set bonuses.
Set Bonus Weight
---------------------
2T7 259.68
4T7 275.81
2T8 104.84
4T8 511.29
2T9 121.54
4T9 412.31
2T10 372.31
4T10 412.31
That puts 4t9 above 2t10, and on par with 4t10 ( although, adding 4t10 and 2t10 against 4t9 and 2t9, t10 wins out >.> )
You're right that they're close, but 2t10 is slightly worse.
Note: this wasn't a bash post, mainly just a note to you.
