Let's stop ignoring this: no priority of party members resolving

[reality_check]

But.... I raise/heal partys member by the "member list", when I select the member on the member list,
my screen will target on that member as well... so if he is too far then i will not able to target him....

The issue is that in large scale fates, you can't even target them through the members list unless their character model is rendered on your screen. The client will choose to render chocobos and other mobs/characters before rendering your own party.
