The predatory FOMO nature of Games Workshop is real and harmful to the hobby as a whole. The editions of the games could last for years yet we're on a 3 year cycle to adjust stats and change rules that don't need changing. It creates a cycle of I liked this edition but everybody moved on so I'm forced to move up or give up on the game.
Luckily there's a million other games but they're micro in comparison. You're stuck either creating a community on your own or hoping there's a group within a reasonable distance that you can help with. If not... Sorry about your wasted investment.
If you do get sucked into it and you end up investing into every GW game system with multiple armies across every system, you're gonna run out of space. Unless you live in a multi story house or have a shed with nothing in it, these things take up space.
