Rogue Partner

[Conscript]

My friend just started playing on P99 and made a Rogue.

We want to play together so I was trying to figure out some decent classes to duo with a Rogue.

I currently play a Necromancer and my first instinct was to power level him the best I can up to my level and then group together with the snare + fear + backstab combo. I figured this was a decent combo since I can throw heals at him, give him open backstabs and with my mana efficiency and his lack of mana downtime would be minimal.

I did some research on the forums and wiki and another option that came up was making a Bard to play with him. I'm not quite sure how this duo works, I assume it is with a bard fear song + bard buffs but it seems sketchy.

I also heard shaman was an option but I threw that away since it isn't a class I favor.

Any suggestions? Is my train of thought with Necro + Rogue correct?

Perhaps Monk + Rogue since both classes have a fear and the dps would make downtime minimal?
