Your squad is missing what Excalibur brings — especially Slash Dash.
You already own the mods / archon shards that make Excalibur’s scaling comfortable on Steel Path.

Slash Dash is often the Helminth sacrifice if your build never needs Ability 1 and you’d rather import a strip, buff, or survival tool.
Keep Radial Blind and later abilities when they define Excalibur’s identity.
Never subsume the ability that enables the rest of the kit’s energy or survival loop.

Strength: Raises damage and effect potency across Excalibur’s Strength-scaling abilities.
Duration: Extends channeled / timed effects — often comfort on Excalibur if the kit leans on buffs or zones.
Range: Helps radius / targeting tools. Dump it if Excalibur is mostly self-buff or exalted weapons.
Efficiency: Keeps ability uptime comfortable, especially on longer Steel Path missions.

Match the priority to your main ability — Strength or Duration first for most kits, then Efficiency, then Range.

Mission / Context	Rating	Why
Steel Path Survival / Defense / Disruption	Excellent	Excalibur is a S-tier Steel Path pick because Exalted Blade still works when every spawn is overlevelled. Summon a sword of pure light and immense power.
Mobile Defense / Excavation	Strong	Excalibur can hold Mobile Defense / Excavation without sweating every spawn, mainly via Slash Dash. Slash and dash through enemies alongside a radial specter.
Exterminate / Capture Speed Runs	Excellent	Speed runs favor Excalibur because Slash Dash skips empty rooms and ends the mission early. Slash and dash through enemies alongside a radial specter.
Spy / Rescue / Nightmare	Weak	Loud kit. Leave Spy / Rescue to invis or silence frames; Slash Dash doesn’t make Excalibur quiet. Slash and dash through enemies alongside a radial specter.
Open World / Bounties	Strong	Strong on packed bounty camps; Excalibur still leans on Operator / Archwing for the empty travel stretches while Slash Dash handles fights. Slash and dash through enemies alongside a radial specter. Excalibur epitomizes the warrior spirit.
Long-Range Gunplay / Eidolon-Style Content	Weak	Excalibur wants pack clear or finishers, not pure long-range; Exalted Blade won’t save an Eidolon-style loadout. Summon a sword of pure light and immense power.
