Just because a battle is meant to be epic doesn't mean it need to be battled. We do could have different perceptions of the same battle depending of the discipline you using...like as DoW/M you being able to straight fight it while as DoL you needing to sabotage a bridge or something (like damaging pillar or cutting ropes) while the companion NPC hold the battle part or having to fix a buch of parts from a damaged cannon or airship as DoH then make ammo and shoot the enemies while companion was distracting them.

...but now we already know that, probably, with the change of main scenario to a battle-oriented content, not only the DoL/H with lose even more importance ingame but we allso might be losing all the companion-related content since DoW/M don't actually need companion for battle content.
