I like it, but mostly because I'm associating "blood" to lineage instead of bloodshed. The word blood itself tends to cause some controversy and leads to a more dark and edgy approach but I think it's mostly a cultural thing, since I don't think the name "STORMBLOOD" causes the same impact on the eastern players.

Plus there's the whole 'true meaning' thing. In the beginning Heavensward was a meaningless name just for the shivers until we got to see the story to why Heavensward is named Heavensward. On a heavy-story-based game such as XIV, I'm pretty sure that even the title STORMBLOOD has potential to grow on people if there's an in-dept meaning to it; and knowing this game it's pretty sure it'll have.

I still think the whole "blood" thing centers towards a lineage instead of a massive bloodshed, anyways.
