That's right - while your damage is on the lowest end of the roles, you're still a part of the team and any damage you can contribute when the party is healthy goes a long way over the course of a dungeon.
>Is it difficult to go from heal mode to damage mode?
Dealing damage with Healer kits is pretty straightforward, all of them have standard damage spells and a DoT. Jobs like White Mages build up a special resource when healing that allows access to powerful damage buttons, while jobs like Astrologian and Scholar can boost the party's outgoing damage or critical hit rate. Healers also have the ability to heal using their OGCD abilities, meaning you can spend resources to heal or mitigate in between your damage casts as well. As long as you're making an effort to always be casting something, you'll be in a better position than most first-time healers at your level.
