Just raw passion/insanity~
In specific "[Player] suggested we do [thing]", it's not very often. Most suggestions are conceptual and not fully fleshed out, which means someone has to sit down and do the full fleshing out prior to it becoming a proposal. Proposals then require detailed write-ups which would be internally reviewed as pass/fail prior to being pushed to eat development time for evaluation/execution. As there are hundreds of thousands of players and millions of accounts, there are checks to prevent a flood of information.
That being said, player suggestions, comments, criticisms, frustrations, and examples are taken up in overarching terms and expressed directly via internal reporting. Pain Points and Problems are highlighted for awareness and if specific/aggressive enough can become a larger topic for discussion/engagement. Stun Bombs was immediately one such topic. -- As for acting on Feedback/Issues it requires it's own process of evaluation, proposal draw, evaluation, execution, testing and more which tends to take months (not to mention having to somehow fit in to an established workload timeline which spans months into the future). Community Concerns tend to move quickly from topic to topic, so fixes to issues showing up 4-6 months after they were initially identified as issues can sometimes go unnoticed.
