@sean1696 Welcome to the game and the forum!
If you really enjoyed Hunter's gameplay, consider returning to the class once you level it up a bit and can unlock more of the skill tree. In particular, once you invest in "Auto-Mate Half" your Hunter will automatically use your Healing mates whenever you fall below 50% HP which is a big help (only triggers 20% of the time at first, but if you max out the skill it'll go up to 100%). You can also invest in the skill "Iron Will" which gives you a chance of staying alive at 1HP after a would-be fatal blow (caps at a 75% chance of survival when you max out the skill). There's also the "Hunter Physique" skill which grants an ability you can turn on which will reduce your damage taken for a length of time while also preventing you from getting knocked back from attacks so you can stay up close and personal.
To level up your Hunter, you could make it your subclass while playing Ranger to grant it some (25%) of the EXP you earn in the field and could also switch to Hunter whenever you turn in quests to give it all of that EXP too. In addition, you could make Hunter your main class while running "Tokyo Keys" (under main quests => bonus quests) which are the best power leveling source in the game (can earn a Silver one each day by completing the 5 daily missions and I believe the current campaign gives out a Gold one each day for logging in).
And just as a bit of background, PSO2 is a little different in that it abandons the classic trinity of roles and pretty much every class (minus Techer) is a pure DPS class. However, many classes have access to the healing spell Resta which can be used on players in the vicinity when fully charged and there are some other abilities that can heal the party too (e.g. the spell Megiverse and Etoile's Over Drive skill).
