There's multiple issues at hand here....
1) "Voxelmancy" is such an arduous process, no one wants to take their works of art out on the field.
2) Safe Zones allow people to play their PVE play style with virtually no risk.
3) Sell bots at the start of Beta allowed massive initial Industry to jump off..... Leading now to an unhealthy saturation of warp drives/cells.... Not everyone should have them and be able to warp from safe zone to safe zone. Warping SHOULD be expensive.
This has lead to PVP only being performed by those that want it. Hence, you are getting ships that are Min/Maxed, true war machines....
Add to this that NQs current model of combat is all about statistics.... More voxels means more life. Filling the build box grants you more engagement time.
Let's also note that square flattened areas are much easier to repair on the fly.
And, people are still testing how the game works, finding the weak points, Min/Maxing .... Your not gonna take the sports car out to go learn how to drive.
So yeah, of course the cube is the meta, it will continue to be. As long as the game is changing, and the combat style remains status quo, there is no real reason to have anything other than an impenetrable cube.
I'm not even going to answer your poll, because your "solutions" aren't going to fix anything. And they have a passive aggressive, egotistical tone that belittles the cube builders. The rhetoric showcases almost 0 realistic DU combat experience. Not everyone cares about "How pretty, and important does my ship make me look today?". I'm ok with a Borg Cube because it gets my butt in the pilots seat frequently and consistently, and allows me to experience the game's combat system readily and adaptively.
PVP is not in a state that I think it should be. But Nerfing everyone, because some people are analysing and building using the constraints of the game to increase ships efficiency/potency, and your choosing vanity over functionality, is just ludicrous.
If you want to fix the cube. Change how damage is dealt and targeting is done. Higher cross sections should be more easily identified, either by range and targeting speed or both. Encourage "Stealth" ship designs, lower profiles and such. And they should change how rounds impact damage works. Right now it's all explosive splash style of damage. There may be different resistances, but it's still all splash damage. A low damage armor penetrating kinetic round needs to be added.Where damage is dealt in a straight line through the ship (to a certain point depending on size, quality....blah blah blah) and the collateral damage, or cavitation, or hole, is very minimal. They should also add a more thermal damage type, that has little effect on armor but wreaks havoc on elements.
What we really need.... Is to stop the toxic "Nerf Talk Meta", who's motivation is holding everyone else back, because we can't figure the game out. And let's work towards real solutions that will encourage ingenuity, and community growth.
