I also use 3 set of gears which happen to be exactly the same as the above post, the only difference is that i also use boon duration runes on soldier gear.
Most of the time wearing the knight set with berserk accesories.
My reasoning is that even if you dodge all big attack , you will probably get hit by a few random ranged attack/aoe.
(Currently at 62 but still have a hard time dodging everything especially when you have to fight in tight zone with multiple target like colossus fractal)
And if you dodge absolutely everything you risk being out of stamina for thing that oneshot/deal agony.
I mostly use full berserk on fights when there really is only one target that deal most of the damage(ascalon captain/ poison golem/norn boss/dredge armor/swamp bosses) .
This dude has pretty much nailed it.
