This is actually a relevant comparison because block and Thick Hide are both passive forms of mitigation…
Unfortunately, I do not know much about Warriors and only have a basically fresh 120 at ilvl 365 or so in live… but on PTR it has a roughly 25% base block rate and about 35% damage reduction from block.
Given that information, one in every four attacks will be blocked, so one quarter, or 8.75% would mathematically be their passive damage reduction from block. Keep in mind this is on a very undergeared Warrior so numbers may be a bit higher on a geared one.
Tical… you keep going back to all these talents Guardians have access to when comparing them to Warriors. But everything mentioned about Warriors is baseline.
We have Ironfur, Frenzied Regeneration, Berserk, Survival Instincts, and Barkskin. Plus a passive 6% DR from Thick Skin.
First row is really between Blood Frenzy and Bristling Fur. Blood Frenzy is good in multi-target and Bristling Fur still requires you get slapped around since it’s based on damage taken.
Second row I guess you could take Renewal? If you want a paltry 30% heal on a 90 second cooldown lol.
Third row will be between Balance and Restoration Affinities. Mostly for Typhoon or Ursol’s Vortex. The bonus 5 yard range from Balance is really handy, Ysera’s gift is okay, but is wasted if you and your party are at full health.
Fifth row we can get more rage, more rage, or 30% more health every three minutes when we Berserk.
Sixth row we have Earth Warden, but it’s not like it’s up anywhere near 100%. If we take that we’re not taking either of the other two talents which reduce the CD on Survival Instincts and Barkskin, or increase the duration of Ironfur and healing of Frenzied Regeneration.
We can then tack on Rend and Tear which takes maybe 18 seconds to stack to three for full effect, and this needs to be done for each fresh pack in M+… or Pulverize which is a pretty decent 20% single target DR but takes 12 seconds to generate the two stacks of Thrash it consumes and has 33% uptime.
Warriors have Shield Block, Ignore Pain, Demoralizing Shout, Last Stand, Shield Wall, Spell Reflect, and Rallying Cry. They also have passive block which earlier was determined to work out to maybe 8% (probably actually more).
First row they can take Punish… basically more passive DR for just doing their rotation. 3% guaranteed. Most likely to average around 6%.
Third row they can take Booming Voice and get a free Ignore Pain when they use Demoralizing Shout.
Fifth row they can take Never Surrender and buff their Ignore Pain or take Indomitable and gain 10% max health plus more healing than a Frenzied Regeneration when compared to its “healing per cooldown second”.
Seventh row all three are great choices. Very noticeable cooldown reduction on Avatar and Shield Wall, or more rage and extensions on Shield Block, or a 33% cooldown reduction on Last Stand that also grants you Shield Block (35% DR on an undergeared Warrior noted above) for 15 seconds.
So yeah… maybe there’s some talents that shore up some of Guardians short-comings, but the talents for Warriors just make them better.
