What is an 'intensive purpose'? If this is an indication of the higher standards of the devs for this steaming pile of pirate poo, I fully understand why the game is the mess that it is.The phrase "kills the game" is being thrown around like candy in a San Francisco candy shop, so let me take a second to address your post in full.
Firstly, the changes to copperhead (beside the slight buff to turn rate) to all intensive purposes were done to mimic the functionality of POTCO's Copperhead.
How the ship had been before was NOT how it functioned in POTCO, and the team has put hours of data collection regarding the ship's functionality in POTCO to make an accurate assessment of how to tweak it.
Secondarily, not everyone will be satisfied with accepting that the previous Copperhead was blatantly overpowered and desperately needed tweaking. As proven by a number of more mathematically inclined folk than myself in the community, Copperhead is as (if not marginally more) consistent with broadside damage to the likes of Stormchaser, arguably the best upgrade in the game. So damage doesn't seem to be a problem, and from personal testing, the ship performs fine at what it's meant for.
Second to lastly, as a game that is in beta, being run by a volunteer team, not everything will be perfect all the time. Bugs will last extraordinarily long amounts of time compared to massive development teams, and the previous version of Copperhead was considered a bug. It was not balanced nor consistent with POTCO, which are the two goals that were achieved with this recent tweak.
Finally, let's get this straight. There are millions of tweaks, fixes, and additions the crew can and may add to The Legend of Pirates Online in the future to create a path toward creating a more purposeful MMORPG, and I can promise you this:
Regardless of if the sky is falling, or some major thing is being added, I can promise that the addition of a single feature has never, won't, and will continue not to be the sole driving force in killing a game like this.
You are being defensive of people that you see as victims but that we see as legends in their own minds. For all the effort put into keeping POTCO running in some iteration, they may as well throw a match on the whole entire thing and start over leaving out any reference to the original POTCO because they have already moved so far away from the original game that it is a farce.
