edit: wont let me link a build damn, dunno why
1- I do not think that cloak of Anni is a must for pvp,but it can be of help I dunno...surely I do think that Quick recovery isnt bad as you say in an ANNI pvp spec, it's nice to have a moderate dmging ability "almost for free", to use it as a filler.
2- Bleedout is must have as anni spec (even if it's buggy , and doesnt work like the tooltip says). Emo may be taken or not in my opinion, depends on what you want to spend those skill points on, if maximizing dmg or get more utility talents.
3- Malice should work on Deadly saber, but not on Rupture. As if I recall well the first is listed as FORCE attack , while the second is listed as MELEE.
