I found White Dwarf went to crap sometime after 2003. The last time I remember really, really loving White Dwarf was during the Eye of Terror campaign era.
Actually, now that I think about it, I remember when I decided that White Dwarf just wasn't worth reading anymore - it was during the Medusa V worldwide campaign event. There was a battle report between an Ultramarines army and some Necrons and the Space Marine player opted to take silly things like a Captain with a power fist, a Land Raider and a bunch of other stuff that wasn't only a terrible mismatch as far as effectiveness and fluff was concerned, but would just generally be worthless (or even counter-productive) against his opponent. At this point, I just couldn't stand the stupid anymore and canceled my subscription. I've only bought two issues of White Dwarf since that day and only did so because they released the 4th edition Blood Angels Codex there.
