This was extensively discussed here Do you thinks this is fair?
And I still think that in this regard RF works as it should - cover is supposed to protect you when someone shoots at you, but to shoot at someone you have to expose yourself and risk getting shot at.
A different issue is that some of us believe RF should work more like it did on release.
IMO RF of teammates of the target is the one that should activate, not of the target itself.
EDIT:
I don’t think that this is an accurate description of what actually happens, because it is an attempt to show almost simultaneous actions in a turn based game.
