i was thinking about trying melee ascendant - but those 3pl ascended wont make even 1 pen - and soulblade can do 3x amplified without problem, then bam bam few attacks and again - when comes to lower level shred skills, she can spam some even more than ascendant, if you chose to - f.e. soul shock 5 focus - and has free almost perma concentration, and almost perma 20 perc weapon damage - seems winner - not only because soul blade
my problem is, that assassin brings nothing seems - guile cost of being hidden is simply too much - and setting up circumstances for good backstab makes usually rest of party without any management far too long, and it often fails - if mobs are moving etc. Assassinating mages is fun but pointless, because trickster with escape wrecks them easily without stealth (arguably easier, because you have to be fast, until they cast their buffs, so quickly escape bam bam done)
I'm using her as a tank & crowd control source, though, not a DPS source. There's an interesting sort-of synergy where she spends the first part of most engagements building-up her Focus & Heating-Up bonus on the front, then when the opponents start to drop she can very quickly shoot-off some ascended psychic attacks, pop smoke & delete someone with a Finishing Blow.
I also have a Soulblade / Bleakwalker for DPS, but it honestly doesn't even feel like a Cipher because the only Cipher ability she ever uses is Soul Annihilation. It certainly works just fine, but it is not what at all comes to mind when I think of the Cipher class.
