Out of curiosity, has anyone tried the "mobile beach-head" approach with the sieges? As in:
1) Clear the wormhole with the normal fleet.
2) Warp in a ff generator.
3) Warp in sieges, make sure they stay under the ff.
4) Place sieges and ff in formation-move and group-move, and move them towards the siege target.
Of course, I forget if OMDs fire through forcefields, but I'm pretty sure fortresses don't
And sorry about the siege shots and ff-bearer bug, definitely on the early-fix list when we have a unity version ready for prerelease.
