Assassination or Combat?

I've been levelling as a combat rogue, and now I want to try assassination, do you recommend it?
Also, it's better swords or daggers for assassination?

I dont recommend assasination spec.
Daggers better than swords for assasination spec.

Well most ppl on server playing combat PVE. also leaders always prefet combatif there is only one rogue in raid imo for better opening burst and beter TOT boost. Assa excel in single target longer fight. assa can do realy crazy numbers, but its totaly different gameplay, depends what you enjoy more. Also much easier for me, you need just track your buffs - Hunger of blood need to be active and slice and dice. Your rotation are literaly 2 spells, mutilate and envenom. In perfect scenario u want envenom buff still active, and your main dmg is instant poison..
Also note that you cant play assa with swords, because mutilate need 2 daggers. You also need specific build for that, u dont build armor pene build bud focus on attack power, crit and haste. Also focus on hit cap due to instant poison proc.
