While it is good to consider wilder changes, on reflection much can be achieved with only limited improvements to existing abilities. The more I consider capitals the more I am impressed by the revision to the Kortul. The ship works, it can tank, it has a good ultimate, it can hold its own against carriers. Its probably the capital thats been improved most by balance changes without it breaking the game, and I'd like it used as a model for further change.
That would mean no major alterations to our three candidates, Guidance, Provoke Hysteria and Animosity. Guidance I believe can be improved by having it apply to ultimates and also adding a moderate antimatter regeneration rate boost. Its an area effect so the boost should be cautious, but then again the Revelation is a poor ship. Provoke Hysteria is so rubbish compared to Drain Planet... how about upping the damage to 1.5/s and the population damage to 2%? It was never clear to me why it wouldn't damage the population rather more than the fortifications. Animosity might be useful in its current incarnation for drawing just one round of fire away, if it had another purpose as well. From the Kortul example I suggest that a % of incoming damage should also be converted into shield points, to help with tanking. Then it would also be useful when the Radiance was already under fire. Feed on their rage!
Of the other weak abilities...
It seems generally agreed that if Shield Restore could be self-applied, that might by itself be a sufficient buff.
I liked Zombies suggestion that the GRG should debuff the target, it fits the description of the weapon. The problem with Adaptive Forcefield it that it just isn't very good, especially the shield bypass reduction. How about 40%/65%/90%? Also 20%/35%/50% damage reduction and some shield regeneration like the Kortul example. After all the ability isn't a passive and the Kol hasn't any very useful weapons damage by itself until L6.
Incendiaries and Phase Missile Swarm are simple abilities that just need large and moderate damage increases respectively. It's a pity that the Missile Swarm can't be made to profit from bypass research.
It has been suggested that the Egg needs a further boost to its colonise ability. The problem with allowing Vasari an early finance boost from colonisation is that they already have one from scouts. Again the current ability is capable of improvement, why not make it 30% or 40%?
Subversion might be helped by a boost to the duration to 300/600/900 and effect to 100%/150%/200%.
There's a list of limited changes that might improve the weakest abilities, nothing radically new. For legal reasons I'd like to make it clear that one of the suggestions was originally made by Warlord Mike.
