Walquiria is a welcomed sight indeed.
Well since you said 2010 I will have to say Carla Novaes is my most missed.
2. Alexia Freire (not entirely sure if she's done anything after 2010)
3. Angel Star (well in her case she hasn't done anything since 2009 I think)
Dany De Castro will get a mention from me as well, even though she has a solo in 2012, I still miss her tg on tg scenes. Not sure if she's done any in 2012.
