If I was to spec 46 mend how should I spend my other points? 27 cave maybe. I would only play with guilds who always have an aug shaman. Thanks for your time.

The question is, which guilds would take you as a second shaman in their groups?
If this is purely a PvE-spec, 46 Mend sounds tolerable (is the frigg worth it?).
Where you put the rest though...

As you wouldn't PvP with that spec (no group would take a mend shamy over any healer, seriously..) you wouldn't need Cave spec as root and disease are base line anyway.
Maybe put the rest of the points into Aug, so you could at least buff some decent base buffs.

I think I will go Aug as secondary thanks

Dont forget to save up money for your respec

Your shaman name to never invite you for rvr?^^

Respec to aug guy.

Vangonaj mate,- from my own experience even cave shams get group invite, why not mend shamys.. give it a try
