If you're disappointed with FM5 in it's current state, I wouldn't expect DLC to change much. It'll add a bit more content, and maybe change up some stuff, but it's still going to be basically what it is. It's a natural byproduct of the circumstances. It's not a surprise, and T10 were pretty upfront pretty early about how little content it was going to have compared to FM4. And why. You won't get serious change until FM6, and even then I wouldn't expect the same amount of content that FM4 had at it's peak. If we're really lucky, we might get back to those levels in FM7, and possibly the next generation of consoles/games won't need to be remodelled so we might not see this kind of drop again.
