Yes, the sims look weird compared to the recommendations. That is due to the following reasons:
• Bloodmallet uses a fixed pure ST talent set for optimized profile purposes (3101031) - that means Doom Winds profile is running without Forceful Winds or Unruly Winds, which hurts it a lot.
• Wolf Bones is the best pure single target legendary - but AoE contribution is low hence current recommendations.
• Wolf Bones requires uptime to get full use, Doom Winds is burst which is inherently more valuable outside of simulations.
Bottom Line:
Both are good legendaries, it depends what you want more of. Doom Winds in fair 1:1 situations and builds is 1-3%~ behind in pure ST but gains on anything with favourable burst windows and crushes it in AoE.
