I'm on Chapter 8 of 9 (+1), and it's been quite fun. There has only been one boss fight which I didn't like so far. Some tips.
Whenever you zone into a new area, always look behind you for shines, the devs seem to love putting stuff there.
You get your first recruit voucher at around lvl10. If there isn't a character that you really want to try out, consider holding off on getting them until you are done with the Story. Those new characters will be scaled up to near your highest lvl characters, with fleshed out Masteries. This can save you a lot of time/resources. Then again, if a new character seems interesting, grab it. Note, you can't try them out before recruiting them..sadly.
Masteries. This is where you will get the bulk of character strength. Also where you get all your Skills. The Defensive tree is where you'll get all the Support skills, so don't forget to spend points in there. Weapons also have passive that you unlock in Masteries as you lvl them up, so make sure to get every weapon for your characters (these also scale up to be close to where you are lvld).
Story and MC. The MC has to be in the party for all the Story missions, but you don't need to play them. Whichever character you place in the leftmost slot is the on you control. If you spend points in the Defensive Mastery tree, you can make the MC into a Support type with good buffs.
Sigils. These are like Decorations in MHW and will allow you customize how your characters play a lot. You'll gain more Sigil slots from Mastery trees and Fate quests (lore quests for each character that also buffs stats).
Anyway, the game is an easy recommendation, can't wait for April when they release the Bow waifu.
