I can't watch the video because: fuck computers.
Venting aside, I'm actually saddened that the Codex lifespan is shortening this much. Makes me feel less secure in my hobby since GW has shown to be less than interested in keeping the same units powerful from book to book in order to boost sales of whatever new thing they want to make money on. Or even worse they aren't releasing any new units and this is just new rules, which sets an even more worrisome precedent for Codex turnover.
Does anyone else not want new Codices within 2 years of each other?
I'd feel better about it if they weren't hardcover. I like the quality of HC, but the 2 year turn around kinda blows given the new, higher price.
