I can't see these on the Shaman Skills bug list, so I assume they haven't been reported?

1. When a shaman respawns, they get another use of Revive (and probably of other limited-use things?). This Revive does not actually do anything if you use it.

2. [fixed]

3. Shaman auto-revive sometimes triggers on dual shaman maps.

3 - Shamans aren't supposed to revive in dual shaman maps.
2- You still receive the gift, no? So they don't really need this fix this along with 1 since it doesn't even do anything at all.
But, they might fix it when you revive, your hearts, teles and ect reset.
