Luna you amaze me.. really you do.. Sacraficing something?? Oh really? Totally destroying your perk setup is not called sacrificing.. unless you wanna call it the sacrificial lamb.. you need to perk not 1-3 but 10 in Spatial Displacement to make it useful+run our root resist aura which negates our Vengence line of nanos from being used as well and even then its not a guarantee.
So lets see what are the options?
We can choose to not perk Holy Mark -evades big time for a pseudo evades class that is highly dependent on evades to survive.. or perhaps we can not train Blessing.. but wait.. where would our healing abilities go since our Nanoline aura is totally useless in anything but a duel and even then more of a joke.. "best heal 870/20s".. or wait we can sacrifice Bio-shielding.. except oops there goes the other half of our healing plus our entire defensive tool kit.. or how about we just untrain Reaver.. oops alpha.. what alpha? All our Dmg comes from perks + our AR to even be able to hit anything "mind you we still cannot perk an evades profession with it".. then there is the brilliant point of view to take a few from each.. Thought of that one.. except.. the amount of perks taken from all of the aforementioned lines would basically negate all of their usefulness... so please tell me where the sacrificing is? We are a 100% perk based profession.. we don't have combat nanos.. we don't have ranged bonuses.. We have perk and pray...
Now.. if SD was a AI Perk... then we could "sacrifice" something for it.. without totally destroying ourselves.. we could elect to give up something like CoHI -AR + few dmg perks.. or what ever else we are using Crusade etc.. But by it being a SL perk.. its just not a viable option without ruining anything else we rely on to survive majorly.. I don't see Ranged professions sacrificing anything to root us...
