Ash Prime is better than Loki Prime. Only thing Loki has going for him is Radial Disarm. If you mod Ash Prime right, his Smoke Screen lasts for 15 seconds which is more than enough time to get out of a heated situation. Blade Storm is also very over powered and can easily kill level 90s. Ash also has the ability to equip the Seeking Shuriken mod, which makes Ash's shuriken remove 70% of the target's armor. Ash is very useful for end game and is probably the best frame for survival imo. I solo'd a T4 Survival for 60 mins with him.
