How is that bull****? They bought capital ships to take down our SBUs as fast as possible. This is against AAA, one of the biggest alliances in the game, they fielded over 23 titans just to take one system inside providence. The field cap ships in obscene numbers all the time, because they know we can't put down a similar sized cap fleet to take them on, and cap battles come purely down to numbers.
As for smaller fleets going on grid with them, they didn't care about us and kept focusing fire on the SBU. Capitals usually pose very little threat to smaller ships, cruisers will take ages to lock onto you because of their signature radius, and dreadnoughts struggle to hit anything that's smaller than another capital and moving.
And as for titans, they can only really kill one ship every three minutes now, and wont get involved an anything other than a cap fight, so that's pointless..
But most cap fleets have support fleets to keep smaller ships off their cap fleet, and a bunch of snipers warping in 150km from the main blob can pick off these smaller ships and warp out, they just need to make sure any interceptors/interdictors don't get too close. It's all about tactics.
