Rogue race and stats

[7thGate]

Really, you should be able to Cap MR and Str buffed at end game in a raiding situation without anything crazy going on. You can add 235 strength with Avatar+Focus+Manicial so you can't not cap that, and pure resist gear is usually not too hard to acquire. Just Focus+Manicial is almost definitely capping you even if Avatar isn't available.

Jayya was able to cap MR/Fire and MR/Poison with ALS gearing and come within 20 points of MR/Cold way before she picked up any raid gear through Aegis, though she was down on HP from high end Velious raid gear. People don't CH rogues usually though, so the extra HP is basically worth an offheal or two at most over the course of a fight.

Asking for the right buffs is higher impact than a lot of this, if you carry Emeralds and ask for Avatar+Talisman of Kragg+Bedlam in place of Focus and Manicial Str, you're still going to cap out STR from Avatar as long as you're over 155 and pick up an extra effective 350 HP for the AOE fight off Bedlam. Remembering to ask for Cadeau of Flame on FR fights and figuring out your Alchemy +resist stacking rules and carrying them causes a big difference.

For non-AOE fights asking for Avatar, VoG and the Ranger +Atk buffs are almost the only buffs that matter, though sometimes you need HP if you want to live long enough to realize you have aggro and activate Nimble to bump for a tank swap.

One thing I'm less sure about though is I've seen some claims that MR doesn't actually cap at 255, either in general or specifically when facing effects with a built in -resist component like one of the two versions of Dragon Fear. Though I've never seen anyone do a statisical analysis of overcapping MR against dragon fear so its mostly anecdotal and I've seen some anecdotal counterexamples with tanks with 370+ MR off a puretone Bard getting feared. If that actually works though gearing to 405 MR is almost certainly best and much harder to do without a Bard, which probably gives Dwarf an edge.

Otherwise I think the minmaxiest end game choice might be a full Cha human to take advantage of Divine Intervention and Robe of the Azure Sky....which reminds me, I need to test the proc rates on that some time to see if they match EqEmu or are different here.
