With your roster, I am not sure why you would bother with Li Xiu. If anything, it is too early to even think about leveling Li Xiu 
It is never too late for pure collection… but to level her past 3.60 it’s a waste.
Agreed. Finish off Gretel (at least to 60). I’d use darts on Delilah, personally.

Ikr, so much unfinish project. I should give leo some love too. 
@FraVit93
I should cut off my yellow collections.they are becoming too many.
@Jalia
I had a very hard time choosing to ascend my first yellow 5s. I literally had to close my eyes and let my hand do deed. And i also know it will be harder to choose between my 2 healers when the next set of darts come around. Viv is just too powerful to just disregard her but Del is the right way to go about.
I know what you mean. I just find that with the amount of mana control heroes around (Merlin, Hanse; & Gretel, Natalya…) it is a lot easier to manage Viv when raiding against her. Delilah gives me more trouble.
My choice was easy - I maxed Delilah because I didn’t have Viv! I did, however, just pull Viv while getting my Panther last week, so now I have to think about my Viv in hand vs. a possible Guinivere or Joon…
Why not - one more yellow to use on a purple tank in AW 
PS - she’s good at farming too with average mana and attack all.
I would rather level any other yellow hero than her. Take Leonidas 2/60 and second chao 3/60 or send yellow feeders into other heroes you wanna level. I see getting LiXiu to 3/60 as a waste of ressources. I got her on 4/70 and barely ever use her
