The game has too big of a paywall, you should have the option to craft the potions and paintball instead of having to pay for it.
Many people like me dont want to invest so much in a mobile game when every other MH game you can craft instead.
Wait until you get to needing weapon and armour refining pieces.
I am not a free-to-play player because I enjoy the game and want it to continue. I buy the season pass and the monthly hunter pass (formerly the Prime Hunter pass, currently the Extreme Hunter pass). For the enjoyment that I get out of it, I spend only a fraction on MHN that I do on beer and petrol.
I’m a normal player and by no means a godly untouchable one. I assure you that the situation will be much better once you have G8-5 or G9-5 armor. Right now, I use 0 potion per day, sometimes I try weapons I seldom use for fun and get hit. But if I focus on my main weapon, it is 0 potion for whole day.
