Having multiple gear sets is important for just about everything you do, and DPS is no exception. DPS and healing sets have many of the same considerations: how long is this fight? Is it mostly single target or AoE? Do I need to have avoidance and/or
普瑞达兹,萨瓦里克的杰作 in this set? Is there something I can use to proc
塞弗斯的秘密?
I have a set that I use for single target with no avoidance or
普瑞达兹,萨瓦里克的杰作 or mastery, a single target set with avoidance and
普瑞达兹,萨瓦里克的杰作, an AoE set which includes
塞弗斯的秘密 because most AoE will be on trash where it's easy to proc
塞弗斯的秘密, etc. I also swap my trinkets around depending on the pull/boss (will the pull be so long that a proc trinket will get more value than an on-use trinket?).
Resto druids are also unique in that they have two completely different approaches to DPS. You can either use
野性亲和 and go cat form and use cat abilities or you can sit in bear form with
女神与爱子 and
自然之怒 equipped and spam
阳炎术 and
月火术. The legendaries and trinkets used for each of these approaches are going to be different -- for instance, you won't be meleeing while doing DPS in bear form so you'll need trinkets that proc off ranged attacks and spells.
Healers also have an extra decision to make with regard to their stats while DPSing because mastery and tier bonuses aren't going to add any DPS. So on top of deciding what trinkets and legendaries to use, you'll also need to decide how much healing a fight is going to need and then adjust your pieces accordingly. On a fight like
融合之魂, you will likely not need to heal at all for 99% of the fight and can put on a total DPS set. Some fights like
鲁拉 will be nonstop healing fights where you can confidently assume you won't be doing any meaningful DPS and so can gear strictly for healing. And then there are fights like
深须国王 where you'll have opportunities to DPS but will also be required to heal intermittently, and you'll want to mix in some healing gear and some DPS gear.
If you don't have a bunch of different DPS sets, don't sweat it. You can start working on them as you get more comfortable, and a lot of it is minmaxing that won't result in a dramatic difference in your DPS regardless.
