"In Tune" states "While fighting Scarlet's Prime Hologram, never hit a hologram without the respective attunement", that requirement by itself is easy mode by definition; simply don't rush. I'm not a noob, currently ranked in the upper 50's in the game having played 17k+ hours and hold 45k+ AP. My current toon is 100% power engineer with rifle. I removed auto attack, got rid of my mech, have only berserker stats, scholar runes and my rifle is berserkers with +5 damage/ +7 crit. I'm going painfully slow, for example I stop attacking 10 secs before attunement ends. If there is another requirement not stated like all npcs in your party must have appropriate attunement also, then this AP is straight up f'd. Obviously, I'll keep trying, but isn't that the definition of insanity.
