I'll nitpick here:
passive mitigation variation with Shield Oath/Grit in. Warriors do get increased healing what brings their eHP close to other tanks combined with Storm's Path, but we're talking about "mitigation" here (also see below)
Warrior GCD/stack uses is wrong. Yes, you get 16 stacks after 24 GCDs. No, it's not 16 stacks in practice after 24 GCDs (Inner Beast also consumes a GCD). It's actually 8,5 GCDs for 1 Inner Beast on average and Fracture isn't even taken in consideration here. Berserk and Vengeance can be used as ways to get stacks as well and Unchained also consumes stacks - Although for paper theory, you could leave out Unchained while it's not the case in practice.
Storm's Path is actually for both tanks for content where two tanks are required
-10% stat reduction is roughly -10% damage dealt that's associated with the corresponding stat. There's been some virus testing data somewhere on the healer forum. Although it's kind of buried with all the facepalm topics in there nowadays.
