That TMD change seems like it hugely shifts the balance of basebreaking back to the defender since TMD is way cheaper than cruisers and part of the reason you could eventually break bases came from the fact dumping a giant line of TMD was never efficient and you had to both waste space so they wouldn’t shoot the same thing and waste buildtime as your engies move from isolated TMD to isolated TMD. It also encouraged slowly breaking TMD since them being spaced out meant all TMD aren’t covered by all other TMD.
This could make it orders of magnitudes more painful to break bases, especially competently shielded ones.
I was also told that it’s a good idea regardless and you could rebalance TMD so that they shoot less often so basebreaking remains the same, except that would now make TML way more oppressive since TMD can barely shoot down a TML in time when it’s in front of the target as it is.
