"1-5 is known to increase your HQ level fast for low level TTKs." <-- Only applies to the boss node. That is why there are suggestions to farm only the first three nodes of 1-5 to prevent HQ inflation.

Cons: HQ lvl 80+ A node has a sub that fires a pre-emptive torpedo attack. If you only have 1 targetable ship (sub doesn't count since it can't get hit by torps) you will eventually get damaged pretty badly.

Yes, this method is decent if you are below HQ 80 and do not have 3-2 unlocked. Otherwise the exp gain does not match the risks involved.
