I used to play a lot of Wh40k and WH, but this was back in 2nd edition. There wasn't much else about that had an in depth universe with the look and feel of old-style WH40k.
Then 3rd came along and while it did do plenty of things right, it also broke a lot of the things that made me like playing. Then prices started to climb into the stratosphere (they weren't cheap to begin with), more editions were released to patch holes in the ruleset whilst making more due to very unbalanced codex releases and it all sort of went to shit.
2nd was hugely unbalanced. But in the sense that there was usually something just as killy or indestructable in the army you were facing if you liked playing that way. But usually it wasn't an army wide phenomena, just horribly overpowered characters/vehicles/squads peppered around the place amongst normal stuff. Except necrons and psyker powers. Or lots of stuff really. But at least everyone could have a go at going OP if they wanted, it was inherent in the system.
I don't know if that's a good thing or a bad thing. But it was a fun game to play back then because of it. None of the other editions gripped me as much, so I stopped playing (other than a little lizard-bird-men force from the "Taalos" codex in 3rd. Or whatever they were called. Free armybooks in WD tended to get my attention more than half of their big releases.) I've still got some chaos marines, some cultists and some orks around in some boxes somewhere, but I don't know if they'll see the light of day again.
Same thing happened with WH really. Prices went up, rules got crappier (IMO), armies got strange. From 5th-6th-7th I was fine with it (BfSP was one of the best releases ever for models and converting), but just couldn't really be bothered with 8th edition. I played O+G and Chaos, so from 5th-7th was already a bit of a kick in the pants for me play-wise. They were pretty broken armies, pretty powerful, but just got nerfed and changed from what I thought was their core play style and fluff as the game editions progressed. Having a Wolfrider and infantry horde all of a sudden have half of it's troops as simple fast cav support, rather than as the cutting edge of the force, kind of turned me off the game. 6th was great, 7th not bad. 8th just kind of shits me. I get it, I'm not bad at it, I just don't like playing it. There's quite a few boxes of wolves wishing a lot of people still played the older editions in my area.
So basically, I turned to computer games. Because they're better. And cheaper. And you can mod the rules in most of them. And there's more people to play against. The only thing GW related that I do play these days is Bloodbowl on Fumbbl (and I'm thinking of jumping into some BFG on Vassal due to a thread posted here). Because I've already paid hundreds (if not thouisands) of dollars to play a game that now sucks balls. Free all the way from this point onward.
I don't think any miniature company will be able to pry me off my computer these days because of GW's shit-house rules, pricing and history as a games company. Their IPs make better PC games than they do board games these days anyway.
