So i have a slight problem, and i'm wondering what the best solution is.
My gear is this

Head: Tier4
Hands: Tier4
Shoulders: Shadoweave
Legs: Spellstrike
Boots: Shadoweave
Chest: Shadoweave

So basically i have mats for Spellstrike Hood in my bank, and i have been aiming to get Tier 4 shoulders or chest the last couple of weeks, so that i still get to keep the 2-set bonus from Tier 4. My question is if i should just keep on trying to get one of those pieces, before i replace my hood, or do i just do it?

Dunno if it's relevant, but if i replaced my Tier 4 head, i would be using it to lock tanking Leo.
