I wouldn't take it so personally because it's likely an issue with the impact of casual play on the game experience rather than a specific dislike of the players themselves.
As with most content in most games, if you pitch the access level for things sufficiently low that someone who plays for an hour a week can expect to hit them in 5 hours, that person will probably think it seems like a well-paced challenge. To someone who plays for five hours a week, it's going to seem a little easy. To someone who plays for four hours a day, much of the sense of achievement gained from reaching a goal is lost because the whole experience has been rendered trivial.
It will be the same when fleet carriers come out. I can guarantee you that no matter how much they cost or how much unobtanium we will need to run them, we'll see a thread telling FDev the cost won't allow them to buy one on their one-hour-a-month account and another telling them that the grind to collect unobtanium is ridiculous and that the dev team just don't respect their time. In fact no, we'll see about 20 of the second one
So yeah. I don't hate casual gamers at all, I've been a casual player of other games and will be again. I don't want to see this game's balance pitched at the casual player though, for no other reason than it won't provide anything in terms of long-term goals for
me if it is. It can't be balanced too hardcore either because that would limit the potential player base, but things taking time is such an Elite trope that it's very unlikely to change. We've already seen credits effectively removed from the game even for players with only a modest amount of time to play,
if that's what they focus on.
Anybody who is a long term player of this game will already be setting their own personal goals because that's all we have left. I'd still like the game to set some for me too though but if they have to be achievable by someone who doesn't play regularly, they're going to be a weekend's work for me and I'm not some six hours a day player. There are loads of games on the market that aren't suitable for casual players and equally, loads that aren't suitable for players who want a more involving experience. Liking one doesn't automatically mean you hate anybody who prefers the other but it does mean you'll (entirely reasonably) not want a game that you like to be changed so that it's closer to their tastes.
