I've looked at a lot of alternate 5E ranger classes, and this new one looks...better than WOTC's 2014 ranger. Unfortunately, this is damning with faint praise. I think WOTC's ranger is weak sauce, partly because the system doesn't offer much if any support for exploration and survival. Level Up has the best ranger I've seen, and that's partly because every class has a healthy dose of non-combat features. LU also has a robust exploration challenges system.
So, I probably won't be using this 2024 ranger as a player.
My big problem with level up is the class does not get spells. You can select the subclass for spells, but then that is tying you to one subclass and that subclass doesn't get enough spells to be a proper Ranger IMO (neither does the 2024 Ranger either from all appearances).
