3rd edition was probably the last good one.I still have my colonel schaefer's last chancers veteran unit lurking around here, a couple of cadian squads and a pair of leman russ, all done up in desert camo. I was pretty proud of that lot.
Then the dropped schaefer's squad before turning it into that generic shitty "penal legion". Basically every change since 3.5 has been one step or several further into the swamp. I gave up pretty quickly, not having the money to afford their rocketing prices, and abandoned the whole thing entirely for greener pastures. Looked back recently, find out they've completely nuked warhammer fantasy and dropped nearly everything that made the 40K world interesting, and realised that I'd got out at a pretty good time.
