T1 subs have two roles:
- Killing underwater mexes
- As a gamble against early navy production (outcome depends on presence of a torpedo launcher and whether the opponent has floating engies).
So I don't see much need for a change here?
T2 subs don't get built much because of torps. Making them harder to target might help?
What if frigates have bigger hit boxes below water so that torps are more likely to hit the frigs, thus shielding subs?
Cruisers vs torps is kind of problematic, because torps are almost the only option if you lose navy and are close to the shore. Navy is just a little bit too strong vs land in my opinion.
