The skirantra without scramble bombers is weak. Period. This was apparent before the buff. It is still apparent now.
I just finished a test game. Went skirantra, but purposefully no scramble bombers. The strat was to use the skirantra to support an early starbase rush, so the skirantra was configured for all fighters to counter any enemy bombers which would counter the starbase, and repair cloud to repair the starbase.
Starbase hit the enemy homeworld and started building. A level1 marza with radiation bomb appeared shortly after and attacked the SB while it was building. When my starbase finished building it had less than 1000 hull points left, and no shields. I instantly started upgrading hull. Also, my skirantra arrived about this time. I brought the skirantra over near the starbase in order to support and heal it. My fighters first targeted and killed the two builders before then attacking the marza.
I had to upgrade the hull on the starbase 2 more times, back to back, just to keep it alive. This was in addition to heals from the much-hyped repair cloud. Also, at some point, I switched the fighters over to bombers, since I didn't see any bombers being deployed. The bottom line is, the skirantra died while sitting there supporting the SB, the SB was still weak after 3 hull upgrades (I want to say around 1000 hull or so), and the marza was still healthy and in range firing away at the SB. At this point, I had seen all that I wanted to see from the test game, so that was the end of it. The marza never had support of any kind - no repair, no escorting fleet, no strikecraft, no nothing. Just a level 1 marza with radiation bomb.
Please, no insults about my letting a skirantra die while supporting it's starbase - WHAT PART ABOUT "TEST GAME" DON'T YOU UNDERSTAND?
Without scramble bombers, the skirantra is a weak ship. Now, if scramble bombers has been overbuffed, fix it, but don't revert it entirely. Somewhere between what it was before, and what it is now, might be okay.
Des is welcome to test out some scenarios with me regarding skirantra. We've played a few test matches - he knows how to contact me.
EDIT: The above scenario may be even worse against a sova, which will lay down missle turrets and have bombers. What would a skirantra do? Now, I'm not suggesting that a starbase rush by vasari automatically succeed. But I am suggesting that if the starbase finishes building and is then supported by a fresh skirantra, the skirantra plus the starbase together should be able to beat a lone capship from another race.
