Hello, good evening, and welcome.
It's all coming back dudes and dudettes. The gutting of army lists conducted in 3rd Ed is definitely being undone.
For those who aren't quite as long in the tooth, 3rd Edition was a much needed streamlining of the game. 2nd Ed, whilst fun had become somewhat bogged down in book keeping. Indeed, if like me you had a penchant for the wild and wacky grenades, the end of turn phase could easily take longer than any other, and combat could be a nightmare. But, sadly it felt like GW had thrown out baby with the bathwater. So many units went bye-byes, and usually they were (understandably I suppose) the wilder and wackier ones.
Lets consider the newly released Orkses. Finally, 16 years later (yes, really....) we have the groovy and fun Mek Guns back, after a fashion. Their rules aren't quite as mental as they were, but they are back. Smashagun, Traktor Cannon, and even a friend from Epic, the Bubblechukka are all restored to their rightful place in any self respecting Orky gunline.
And it's not just the Orkses. Imperial Knights - originally an Epic only unit are now out there, stomping heads and blasting holes in an army near you. And I'm loving it. The colour and character that these units took with them are back!
But....what long gone unit are you hoping to see make a welcome return to the maelstrom of battle?
