Celestial + Expertise & Concentration
Concentration and Expertise were always “stats”, they just weren’t named such. It would first be better to look at why condition and boon duration were not initially on the celestial gear rather than not being added post-update. Maybe they should be added, but this would definitely put Celestial way over the top even if an 8% reduction were factored in; it would need to be a greater reduction I think.
Also, weakest by which metric? In PvP, last I recall, it’s still quite the powerhouse amulet, at least situationally. It is surely not built for damage in PvE, but you would find yourself dying much less frequently wearing Celestial as opposed to Sinister/Viper/Berserker.
I think they should just add the new stats on to celestial. I don’t think it would need any nerfs or anything. With the lower point allocation the boost to con duration and boon duration really wouldn’t be the huge but it would help to make celestial worth the investment. Currently I don’t see any reason to not either go full berserker or vipers with some rabid mixed in for pretty much 100% of pve content. In HoT maps I have been taking off my ascended celestial gear and putting on rare zerker gear instead. /as it makes things so much easier there for me. IMO it should not be easier to do things in rare gear than it is in ascended regardless of the stat combos but especially with any gear with some offensive stats. For optimizing there will still be stat combos that are much better. For example vipers with either rabid to maximize DPS or dire to add some tankiness. For a condition build It would e pretty silly to put on some celestial when you could just do fore mentioned. We all know that using zerker on a power build is the way to go. Adding some boon and con duration just makes celestial not suck as bad but it still won’t be OP or meta or even come anywhere near the meta builds except.
