The Ranger is a more... unconventional Cleric, as this one has very little healing and support, and more damage and buffs / debuffs. It can be good sometimes, but in my opinion you can benefit more from playing a Mage for the crowd control rather than the Ranger, which falls somewhere in between.

Since the Ranger has both damage and some support, you will be a good asset to the team, but obviously won't make such a big impact as a Priest. Either way, it has a kinda unique play style combining many things: healing, buffing, damage dealing and summons.

Skills:

Fairy Arrow: Fires at the enemies, dealing damage multiple times to the enemies in a line.
Enhanced Song of the Forest: This skill heals the nearby allies over time, and buffs them, increasing the damage they deal.
Praise of Blossom: Summons a gigantic fairy flower which deals damage to the enemies in range.
