You both know this for sure? You've been to Frontiers offices and checked with them to make sure they're not doing anything about it? I'm frankly amazed how small player groups crash between one drama to another as if it's literally the end of the world and then blow it all out of proportion throwing out sweeping statements like 'it's hurting the game' and 'they're ignoring their player base'. They fix one thing and then the 'we've been nerfed' brigade come out with torches and pitchforks to vilify them till the next drama swings along.
Perhaps a little less alarm-ism and a little more reasoned and level headed discussion would lead to more developer interaction. Nothing like a bunch of people stomping their metaphorical feet and demanding attention to endear people to your cause right?
As for having more important things to do, they've already told you what they're working on and balancing is an ongoing priority. It's simply a matter of trying (with everyone from either side of the argument simultaneously throwing their toys at them) to walk that middle ground.
I personally haven't a clue what they discuss behind closed doors, but it's clear that if anything, the issue has been exacerbated as of late so no. They have not done anything about it. Arguably they've made it far worse with engineers and soon with Grom's fantastic missiles.
