Honestly i haven't used the phase ships much, mostly because they are generally useless. since they are so vulnerable without shields and you can't do anything while phased AND your flux is pretty much a delayed deaths sentence. 1v1 works, sure, but anything more than that is kinda useless. IMHO it all comes down to Dakka: When there is not enough Dakka means you need more Dakka.
you got to know how to use it.
i fly the Shade with deadly results, for the enemy.
you don't want to stray too far from your fleet, because the enemy has a high bounty on your head.
i find the best way is to use the longest range weapons available, which means Tac Lasers, with the Advanced Optics for extra range.
3 of them is all i need.
with this set-up, it can outrange a Hound or Buffalo in a 1 on 1 fight.
but the Shade is best used in a support role.
and yes, you can do things while phased; make the enemy very nervous and divert their attentions. lol
hell, i should make a video for you folks.
