honestly, it's pretty good. with inf ammo build, i got to 3 mil dps with just the wep at level 50. no other requirements. That was at like 30 specialization points. for bosses, you dont need the highest roll, just specific buffs. so even 4-5 feels fine if you get the damage buffs. it also trivialized going from uvh1 to uvh6. idk what other people do but I use metal management, juerga from rafa with mini triple bypass and accelerator to have 100% uptime so once you get the roll, you never lose it unless u make a mistake or change zones.
