2- I have big doubt about which support should a take as main. I am between an eca support or a masq support I love both gameplay.
First of all: Don't worry to much which one might be generally preferred, play the class you enjoy.
I as well would vote for Ecaflip. Maskeraiders might be stronger direct healers and better at positioning, but Ecaflips can easily keep a cooperative group in a healty state, everyone likes additional Crit & MP and Maskeraiders are a bit more endangered, since they're getting double damage in the worst case. Two of their elements also support a meele oriented playstyle, while being ranged optimizes their healing potential.
