Decided to test an avoidance guardian build which could reach 100% avoidance purely from guardians ward being active. An interesting side effect of 100% avoidance is that adaptability (which only triggers when actually hit) will never activate so I could save a legacy slot there at least. I should probably preface this by saying that I do not play guardian on live so my knowledge is pretty sketchy, when doing these pulls I was not attempting to put out any dps and I pretty much only stacked fortitude to 5 stacks before I maintained ward spam. What I did find was that I never required anything other than warriors heart to keep me alive, for the most part my blocks were healing me enough to pull through; this means that I never activated juggernaut or pledge to influence these numbers.

Wasn't able to get a good parse on the 2nd group of RC, that troll kept ruining everything with stuns and constant disarms.
This guard build still maintained 42.6k morale unbuffed and utilised the new 2 slot pieces for warriors heart so you don't really need to sacrifice much to get 100% avoidance.
Unbuffed BPE is as follows:
* Avoidance type: full chance / partial chance / partial mitigation / rating
Block: 18%/29.6%/55.6%/22,575
Parry: 19%/28.2%/54.7%/24,099
Evade: 13%/30.4%/57.8%/27,549
Physical mitigation was at 32k due to the sets and jewellery giving way too much.
Tactical mitigation was at 21k unbuffed, 24k with ward active.
Crit defence was at 63.8% (including the 10% blue line buff)
I did not use the power restore essence as the morale was giving me more than enough fate to regen my power.
Overall I think it is fair to say that partial mitigations are pretty easy to cap and could be well worth capping in builds at this point.
