I think it's a good idea and I think taking some time to really focus on not just squashing bugs but also general polish and improvments on the whole experience for the end-user(us) would be mutually beneficial, and as we all know happy customers is good for business.
Visual
I've seen the reconstrected athene/zephyrus area aswell as the long overdue redesign of several mobs and I'm genuinely impressed however, I think that other key factors should be improved than just the static eyecandy in form of textures, terrainmeshes and vegetation. Animations for starters. Mobs, vehicles and avatars especially mob getting hurt animations that feels jerky could use some TLC.
And there are many models of nearly all category of items that could use a proper facelift.
Gameplay/Interaction
General controls in the game could use quite a bit of polish aswell, is the game fun to play, Does it feel right to move about with your avatar? Does it feel satisfying to drive a valkyrie in the world or is it like riding a breadloaf in mustard? I'm not talking about added realism but small touches to make the game feel better and be more enjoyable.
And perhaps a redesign/simplification of the rather complicated task of remapping the controls on the keyboard, the action book is not the most user friendly system especially for new players.
Another thing that I really miss from old PE is building oil towers by stacking barrels of oil (anyone remember the oil castle?) I know it's still possible to some extent to stack objects things but it requires much more work nowdays. And if it was disabled due to conserve server performance, well let's put it this way in an RCE nothing built of objects a tt value won't last very long, besides it felt great to build something and leave a few peds value of materials to some lucky Explorer (perhaps such find made it possible for him/her to get the first profitable hunt/miningrun/craftsession that helped them get hooked) not to mention finding such treasure as a noob
Some fun actions could be added aswell say for example one crippling your avatar turning it into a ragdoll for a few seconds letting us play a bit with the ingame physics that CE2 provides or more basic ones such as crouching, and the old sit/lie down on the ground.
Audio
In the auditory department there's much room for improvements, some weapons sounds are just horrible, the "starkhov type" blp rifles and the mini-sweeper sounds springs to mind(the one that was used before was loads better when hunting for extended periods of time imo
) Putting some time and effort into the sound effects eg. making everything from guns, tools and vehicles to menu beeps sound better on the ear.
"Chat voices" could perhaps be re-instated aswell, I think that they were great on building atmosphere and helped giving the game character. I still remember in 2006 when I first logged in walked out of the spaceship and walked into Port Atlantis hearing those nonsensical voices. As far as as first impressions go it made a huge impact on me.
I guess some might find them annoying though.
I think the ingame soundtrack is also outdated and as MindArk is stationed in Gothenburg they could perhaps enlist some of the brilliant musicians and groups that reside or atleast originates from the same town and happens to be creating music that I think would fit the game perfectly, and they are Solar Fields and Carbon Based Lifeforms(I'll leave youtube links at the very bottom of the screen if anyones interested in listening to them)
I am aware that many people play with the ingame sound muted and with their own music instead, but I think it's important for the ingame atmosphere.
One might argue that these minor issues aren't imporant but as an avid gamer for many years the games that I clear the settling dust from and play from time to time that are the ones I list as my all time favorites have one thing in common great balance in all aspects: gameplay, Audio visual, atmosphere and overall quality.
TL;DR MA/Dev should halt content injection in order to proiritize bugfixing and overall quality polish; Many small details makes the big picture.
