Okay, I over-estimated the titan and war situations you were facing. Based on the way you talked about emblems I also assumed you already had 2-3 top shelf options in all classes; it sounds like you are saying you’re just unusually talented in the relevant classes because of RNG, etc.
Based on this new information, I will now update my opinion: I now agree with those who say Evelyn 3.70 will be serviceable for now and you should go a different direction. I look at both Lianna and Kingston as very compelling options and would make the final decision based on what else you have.
Ultimately, I’d choose whoever does something you can’t otherwise do. Factors like: if you already have a powerful complement of attack debuffers (say, Scarlett, Richard, and Skittleskull), then that’s a negative for Kingston. And, as AirHawk points out, your mana troop is relevant - if Lianna’s costume shaves a tile, that’s a benefit.
