Id' still love to see TEC Loyalists' Titan 'Group Shield' ability made passive. Of course not costing AM would change its effects.
I think it should increase shield regeneration and max shields at least.
It should also spread part of the damage to all shields to make it harder to kill any single ship, using e.g. sniping.
And either have it increase max shield mitigation for the ships under it, or raise shield mitigation even out of combat, so that ships enter combat with shield mitigation 'hot'. Or both.
I am not delving into numbers because frankly I don't know which would be reasonable values.
The strategic ramifications of a passive, always-on vs. AM-costing, triggered ability are nice and would be a nice improvement for the loyalists' combat-readyness. It would would also raise the Ankylon's priority as a target on battles.
