Yes, tank is a bit vestigial.

Archer should be very good (like, warrior tier) with a full tank but should not refill out of water at all. That makes the mechanic interesting and enhances the water synergy.

It still makes sense to use such unit on dry land. It's effectively one-use for the main purpose but can still be used to scout or harrass naked expansion later. Think Roach which survives as a Dirtbag on explosion.

The main problem here is that Scallop is already warrior tier without the downsides, AND has torpedoes in water to boot. Ideally there would be no torps from underwater and things would have to surface to fire, which gives these two even larger overlap. Archer would be the more interesting of the two though so something would have to be done to Scallop.

"I'm picking a mixed factory on a dry map and i expect it to outperform dry land factories in direct combat without having to ever touch this revolting water"

The archer tank doesn't really work well in current ZK but that doesn't mean it's not there for a reason. If anything, more amphs should rely on water.
