Any Class Help Blue Mask

As my main class approaches endgame, I go through the process of replacing old gear with the higher leveled loot I find. I never found any reason to get rid of one piece though: my blue mask. I don't see a blue mask used in many good endgame builds though, unless it's a build that needs a lot of skill points.

Why don't people use the blue mask more? A good id mask gives a 15-20% buff to all base stats. While other endgame builds offer things like hp, mana regen, and poison, they don't really give that much of a raw stat boost (unless I'm mistaking how skill points are used w/ base stats?). Not even the stardust's 2/4 MR should make up for the halved stat bonuses.

 

stardust is MUCH MUCH better

 

Why is stardust better though: instead of 15-20% buffs to everything you get 7-10% buffs (again, if I correctly understand how the skill point buffs work) + a small mana regen boost. Even if so, I don't see many stardust builds either.

 

+2200 hp
+2/4 mana regen
+100 elem defs
-10 skill points

 

Ah, forgot about the elemental defenses. Though it really is -50SP...

 

who cares, if you're using bmask/stardust its more likely a rainbow build
