I see a lot of people saying world/wilds are easy, and they definitely are muche asier than MHGU and older entries. However, people tend to forget (or simply didn't play old MH) was difficult due to bullshit hitboxes and overanimated actions like healing/sharpening/traps etc. Not the sole reason, but definitely a big part.
Believe me I LOVED old MH games, I have 1000+ hours in MHFU and MHGU, but the QOL changes that World brought are fantastic and I would never want to go back to old mechanics.
That said, Wilds' Gore Magala is old school tough fucker, Seregios and to lesser extent Lagi/Mizu were not cakewalks either. Randoms ALWAYS cart to them at least once. I feel the monsters with best gear should always be tough just like Gore where you MUST play with proper preparation and patience. I have high hopes for G-Rank expansion.
