From a world design perspective, I see how they might have gone back a bit. From a gameplay perspective though? Absolutely not. Rise completely trumps World in terms of the smoothness and variety of the gameplay. The wire bugs are game changers and the online is way more streamlined like the old games compared to World.
MH rise was, mechanics, better than the world. The gameplay was fantastic, try to play World before, gorgeous graphics, but the gameplay-wise seems less variety.
