All but 2 of my calcs have the same land/recall outcome as before.

The first difference is that Zik Cr can no longer roid Ter De, but still can't roid Ter Bs. The calc vs Bs looks good if you assume Ter will pick Syren as anti-Bs, but Drake is actually the better ship. Both options are out-inited by both Bs fleets, anyway, but the Drake has the additional bonus of being really good against Zik Cr. That means Ter Bs is still only vulnerable to Cat, itself and Xan Fi. Another downside is that Xan now needs Siege before they get anti-Cr.

I don't think the impact the change had not Zik Cr vs Ter De was bad, though. Ter De was one of the weaker fleets, and this has made them nicely balanced.

What would happen if Syren was just way better against Bs? Like init 7, maybe even 6? It'd make Ter Bs immune to itself, while Ter De would have to stick with Drake. That in turn makes Ter Bs vulnerable to Zik Cr. It would also make Cat Bs even better against Ter Bs because they can fire at Syren with T1.

The second difference is that Xan Fi can now roid Xan Fi. This is probably because of the change in Effs, because switching Revenant anti-Fi from T2 to T1 obviously can't make the calc worse for defenders. Beyond that, you're right, the new Fi effs look weirdly high, but all other calcs come out the same way as they did before.

Overall, I don't think the change made Xan Fi weaker. Maybe raising the Banshee's Cost and ERes by 10% might do the trick? Or 5% on both Xan Fi? That might flip the calc for Xan Fr attacking Xan Fi from a recall to a land.
