Well IMO the effect of stamina reloads has been to increase the dps of the HWATCHA, which was until now mostly a support disable weapon on the goldfish is now a kill weapon. As for the getting on a galleon as a squid yes that is probably easier, however as a carro fish with your engines sticking way out to the rear they are a target now for a stamina hwatcha shot while you are trying to maintain station for your gunner to hit the baloon when dealing with goldies or galleons, not so much spires.
A lot of discussion here talks about how the hwatcha doesnt do well at range, but I would like to remind everyone that meta ships have always been close range ships, mostly due to ease of use for gunners. Which is why we are seeing this giant increase in hwatcha ships.
As for getting beat by noob players, more than likely if your a level 45 and you get stomped by a level 8 hes probably on a smurf account.
