Fighters are the best counter to strikecraft. Relying on a Kol's Flak burst isn't going to work if the enemy has multiple caps with cap countering abilities. Sounds like you just needed more ships.

The Revelation is probably the least used cap. The "ultimate" lvl 6 siege ability is rather lackluster (visuals are cool though!). And Guidance is a pretty useless ability as well. Reverie and Clairvoyance are good abilities but not enough to make the cap competitive with Motherships and Halcyons.

Provoke Hysteria (the Revelation's ultimate) works best on planets with max HP, being able to deal 40% damage in 40 seconds (or 2400 planet bombing damage on a 6000 HP planet in that time).

Three Revelations is a strange choice... Progenitor and one other cap would probably be better as the other two caps.

However, ships affected by Reverie should be knocked out of it if they take a certain amount of damage (the damage requirement increases with level).

There is, however, the Domina Subjugator's Perseverance ability: in addition to repairing the target ship at 25.0 hull/sec, it also makes it immune to disabling abilities, meaning capitals under the effects of this ability are immune to Reverie until the effect expires or the Subjugator is unable to recast it (either disabled or destroyed).

Exactly. You need three level 6 Revelation Battlecruisers where a single lvl 6 Marza or Vulkoras will do.

Revelation = horribly useless siege cap. Buff Hysteria, pls.
