Yep, this standing pvp is just a big mistake, range classes are not supposed to stay at one place so it is not so big surprise that in standing pvp they have some disadventages.
And even heal should be considered as good party skill like before, when 3k dmg single hit from custodi was maximal dmg output of a mob.
I agree that fa is most annoying bich in tg, im one of them after all, in most cases unkillable if he dont want to. And yes, fa should get... something, with which this class can be more useful for party, better heal/buff/synergy, or in all future dungeons (+E3) will be this class just a fifth wheel in a car.
