Definite yes for Gravity. I liked it and always want to reward Marvel for introducing new characters.
I get that creators are less likely to create all new characters for Marvel since the company then owns it - might as well save good ideas for creator owned efforts. I also get that even when creators do invent new characters they don't resonate with readers the same way legacy/spin off characters do.
Even so, I like when it happens and want to support Gravity for that reason.
