Since OP is talking about talents and not about passive skills, let us leave it at that.
My draft before realizing someone beat me to the punch:
Can anyone remember of a ranger class hero with no damage dealing specials able to deal their pierce talent via tiles or slash attacks? All I can remember is that pierce only gets triggered, at a chance, when the hero uses his damage dealing specials. If so, Pierce is lost on costumed Rigard.
As to wizard’s talent, jinx can be activated either thru the specials or thru their regular attacks (tiles on offense or slash attacks on defense).
As to Sif, I think the evade talent is not totally lost on her. She is a holy hero and their counter have a ton of dispellers (Kageburado, Sabina and her costume, Onyx, Ametrine, Seshat, Domitia, etc. ). I love battling Sif as the middle hero in double raid defense formation as I use my mono purple of costumed Rigard, Panther, Alfrike, Kage and Ametrine. Sometimes, I hear myself cursing whenever Sif managed to dodge the dispel. With her surviving the snipe or hits from my dispellers, she manages to survive longer for her to cast or recast her riposte, and more durability to her allies.
As to BK, I’d hate not seeing him as barbarian (and maybe ranger). Imagine if he has, instead of bleed, either revive talent, or evade talent, or protect talent. He would be a nightmare to deal with.
