Skill tier formula hasn't changed, though there's more relevant tiers now due to additional skill gear. Accuracy varies but for the most part it's pretty low. Might try meat in my next party, definitely capping with pizza + full STR/attack gear (ring/back included) on EXP mobs. NMs don't seem all that evasive either, the ones I've meleed I've capped acc with pizza.

Skill tiers yield 2 base damage.
EDIT: On this note, some tiers at 85
base skill: 331 * 0.11 = 36
Magus Jubbah: 346 * 0.11 = 38
Mavi Tayt +1: 356 * 0.11 = 39
From here we have 3 sources of skill+5: Mavi Tayt +2, Mavi Tathlum, and Mirage Keffiyeh.
361 * 0.11 = 39
366 * 0.11 = 40
371 * 0.11 = 40
There's also Mavi Scarf, which would grant a skill tier in combination with a single skill+5 item (breaking into the 40 tier). Not worth using in tandem with Mirage Keffiyeh and does not break a skill tier with two +5 items.
skill with merits: 347 * 0.11 = 38
Magus Jubbah: 362 * 0.11 = 39
Mavi Tayt +1: 372 * 0.11 = 40
Mavi Tathlum: 377 * 0.11 = 41
*Mavi Scarf does not increase your skill tier at this point. 381 * 0.11 = 41
Mavi Tayt +2 OR Mirage Keffiyeh: 382 * 0.11 = 42
Which is the highest skill tier worth reaching at this time. Mavi Tayt +2 + Mirage Keffiyeh + Mavi Scarf would reach 43, but it's not worthwhile. Ideally you're using AF+1 body, AF3+2 legs, and AF3 ammo for your skill tiers at 85.
