With multiple sources of gear (raid, M+, PvP, crafting, world quest, vision) and systems like titanforge or corruption we have to sim every piece of gear to see if its even an upgrade. We are living in the wild west of gearing and it sucks. I feel systems like titanforge or corruption are taken from diablo 3 but its only half of the system which is why its broken. Its all about how you create a build. Your build in wow is a change of talents and possibly a change in stats where loads of gear could be used, which leads to the need to sim everything. A system like titanforge works in diablo 3 because your build is based around set pieces and set bonuses so as you get a titanforge (ancient in diablo) if its of the wrong set you know its not an upgrade and there is no need to sim every piece of gear.
So option 1 is they could make gearing even more like diablo with creating multiple gear sets to bring structure to titanforge or corruption gear. were the set bonuses are more powerful then any titanforge or corruption gear that would break the set.
Pros
return of a BiS list
possible rotation changing sets
only needing to sim to create a build
Cons
possibly the set you want dropping in content you dont want to play (like PvE not wanting to do PvP and vice versa, though i think there is a work around for this)
balance of sets ( though probably easier to balance then current corruption )
enough sets to fit everyone’s play styles ( myself i fistweave vs mistweave, and my friend runs a thermal void build instead of the glacial spike build )
Im sure there is probably more Pros and Cons these are just the easy ones that came to me.
Option 2 is they remove all titanforge and corruption systems.
Pros
return of a BiS list
still needing sims but much less frequent
current builds remain valid
Cons
for those needing to over gear to clear content this would hurt there ability to clear that content. ( there could be an upgrade system like at the end of MoP and WoD this just through out the expansion to gain 10 ilvl on gear so normal gear remains better then LFR gear and Heroic remains better then normal etc )
Option 3 we continue to live in the wild west of gear and sim everything.
Open to other ideas if anyone else has any. This is just my view and current thoughts on gearing in wow
