Sword 2 healing replacement?

I haven't played my weaver since the sword 2 nerf and now that I've played it a little, the healing nerf to it really hurts bad. It was my go to emergency healing. Now that it isn't as good, should I replace Signet of Restoration for a better heal in place?

Context: WvW.

Riptide is still effective evade and self healing tool through comboing. Blast the field with earth2/4/5 or leap out of it with fire2 or air2 for a combo heal (Leap heal scales slightly better with healing power than the blast). The choice of heal skill depends on your build/stats, I've been actually roaming quite happily with Aquatic stance (using stab on stance trait) on my hybrid build that has only 400ish healing power, while my friend runs marshal and signet gives him great sustain.
