I am rather tempted by this but also, I kinda wanna stick with my Wind Torque. I'm not the best person at understanding game mechanics so would someone be able to help me out? Stick with Wind Torque or is Piper's better overall with the CHR (or does that depend on my setup?)
The reason this is so confusing is because most people look at ItemA vs ItemB. You need to look at the entire gear set to understand which is better than the other. You also need to consider when one is better than the other, as most items are not full-time pieces, and are otherwise useless or worse off in other conditions.
For example, Say you have 100 CHR. Is it worth getting another +5? What about if you had 120 CHR? 130 CHR? 140?
Also consider-When is CHR useful(debuffing, resisting, etc)? When is Skill useful (buffing, debuffing, range, etc)?
This also goes along with what you need (end-game? casual?), as well as your playstyle (do you care about buff potency? debuff resists?).
I could tell you both pieces are useful, and I would use both (Piper's Torque for Wind Debuffs and Wind Torque for Wind Buffs) -- But you are not me. I maybe very different from you in every aspect. I don't know what your gear/build/playstyle is and I can't recommend which is better for you.
