I blame multiclassing for that. Becose Sneak Attack bonus is scaling up to 70% (75% with Prestige passive) and combined with scaled Soul Whip it will be...hm, too much damage.
In fact, most of abilities was nerfed, ONLY becose multiclass sinergies makes them too OP.
I mean my preferred "redo" is to have it deal lash damage. The more I look at how Cipher is set up compared to the other weapon-based class options the more disappointed I get, and the very existence of Rogue makes changing Cipher dicey.
In a perfect world I'd want Cipher to have a skill progression like other martials (many of their abilities are just improved versions of lower tier abilities). But in a perfect world I'd want Soul Whip to count as a shred effect and be a 10% Lash, returning Focus equal to its damage. Biting Whip becomes 20% (maybe halving focus return), Draining whip becomes triple focus return.
