Yeah I saw the trailer for Harvestella, it looks rough atm just by the gameplay footage. Hopefully some improvements will come, anyways. I believe the biggest draw to MH Worlds was it's superb graphics and excellent controls. 

Just replaying MHGU has me realizing just how much better the weapons feel in Rise. There is way more maneuverability in Rise, like in Rise I have a more responsive dodge and directional input whereas in MHGU I have to pray I can mash B at the right moment to not get flattened by a damn giant bull frog. To say the least I am deeply regretting my decision to get rid of my copy of Rise last year before the DLC was announced.
