Right now as it stands, Shadow is at the lowest for anything with more than 1 target. Other classes have more tools at their disposable than Shadow currently does. The argument can be said to just simply multi-dot mobs and mind sear, refresh, repeat, etc. .
But that isn't something that is viable. There needs to be something to bring Shadow up to where other casters are at right now. The 30% damage hot fix to mind sear simply wasn't enough, nor has it been strong at all.
I propose two options that could very well boost this crisis affecting Shadow Priests currently. Both of which is comparable to other classes :
1. Make Mind Sear act like a Death Knight Pestilence, where you can use Shadow Word:Pain / Vampiric Touch on your main target, and then mind sear will then spread a shorter duration of those dots. I think having them at full duration might just be too strong, therefore not a wise choice as that wouldn't be working as intended.
2. Boost Mind Sears actual damage by a higher percentage than just the 30%. I believe that an additional 25% would effectively boost the damage of it to make it comparable to other classes. Granted, there could be more of a % base that could make it even MORE viable.
I'd really like to see something done about this plague. Shadow has exceptional single-target damage and I'm very pleased how they've handled that, but anything with more than 1 target makes it lack comparative to other casters. If anyone has something to add, please feel free add more suggestions. I love Priests more than anything, and it makes me sad to see this be a big issue. Thank you for your time.
