Modal wrote:I think again, for most people, for most purposes, you can gear according to the following rules of thumb (for raid boss tanking, and assuming adequate threat stats will mostly come along with the rest):
1) Stay 540 defense, minimum
2) Stack stamina and armor
3) Skip any piece with block rating, unless it has way, way more stamina and armor than another piece
4) Make sure you don't totally ignore hit and expertise
5) If you want to socket a purple gem in a red slot to get a set bonus and/or activate a meta-gem, consider Agility/Stam first, since Agility gives armor. If you really want more avoidance, use Rating Buster to decide whether parry or dodge is better given your current gear. Err on the side of parry if it's very close, because of raid buffs (or, get some raid buffs and then check).
The end.
Ratios are interesting from a theoretical perspective, but since how much defense, dodge, and parry you have is restricted more by what high-EH gear is available than any other factor, for practical purposes you can forget them.
If you aren't picking up at least two pieces with block rating (shield itemization makes the first piece a no brainer of course), it's not likely that you're going to maintain unhitable status. None of our tier pieces will have block rating this go around.
Let's look at a player in known ilvl 232/245 pieces: 5/5 Tier 9, Saronite Swordbreakers (wrist), Clutch of Fortification (ring1), Loop of Twin Valkyr (ring2), The Arbiter's Muse (neck), Belt of Blooded Scars (waist), Greaves of Lingering Vortex (feet), and Satrina's Impending Scarab (trinket1). ilvl 239 pieces: Titanskin Cloak (back), Sorthalis (main h), Bulwark of Algalon (off h). ilvl 226 piece: Heart of Iron (trinket2).
Full buffs, Stoneblood, AGI food:
556 dodge rating
205 parry rating
776 defense rating
37 block rating
443 AGI
3.2 post DR Avoidance: 58.39%
Block: 43.56%
Block+avoidance: 101.95%
If Scorpid Sting/Insect Swarm is on the boss, you'd be unhitable. If not, you're short 0.45% versus level 83 mobs.
