Yes with all the changes and additions I will get at best 15 Agility but am gonna try the 5 Dodge chant to Bracers as well. That would put me at +/- 187 Agility with an additional 5 Dodge and 6 Crit (unbuffed values). The Agility bonus + 6 Crit should easily net me very close to 100% Crit, the Agi + 5 Dodge hopefully will net me low to mid 90's, but since it's not something math can solve because we don't know exactly the number value Blizz devs put on DR and how fast it ramps up to infinity I'll have to wait until I actually have the gear and test it. In any case I will have created the highest damage capable Rogue (as far as Subtlety goes) with an insanely high unbuffed Crit and Dodge value and it's all in fun anyway, pushing the limits of what one can and cannot do.
+6 Crit = 11.145 Crit Rating.
+15 Agility = 4.5 Crit Rating [1 = 0.30] & 3.15 Dodge Rating [1 = 0.21(I'm already at DR for Dodge at roughly ~80%, no known Crit DR)].
+5 Dodge = 9.418% Dodge Rating (before DR).
With the above numbers (and since there's no formula that can 100% determine the post Dodge %, I'm guessing there) I should come up with ~96% Crit and ~90% Dodge fully unbuffed. Yes it's not 100%-100% but it's damn close and far higher than most Twinks ever achieve as well as shows the true limits of the post nerf Rogue Dodge Twinks. The +4 Agi pot would close me in on about ~97% Crit and 90.5% Dodge.
EDIT: Getting 100% Crit is super easy, all I would have to do is change a few pcs to have +crit on them considering 1 Crit is worth slightly more than the crit from 6 Agi. So if I changed to dual Balanced Heartseekers (4.32% Crit) vs 2.4% crit from the Agi on my weapons now, changed to the BOA gun (which I do have on my Warrior) that'd be 1.86% crit vs 0.6% now, etc. That ~96% could easily be 100% at a loss to Dodge, which is my goal, to see how high I can raise BOTH simultaneously. So 100% Crit unbuffed IS achievable, 100% Dodge doesn't look to be but over 90% unbuffed DOES seem possible, it all depends on how hard DR hits me since I'm using Agi to gain Dodge mostly with only a little actual Dodge stacking.
