Sorry you didn't enjoy your time . But let me point something out, before you write it off.
1. The Combat-Wheel isn't RNG, you can aim it and select any move, so in theory. you can select the best attack each time. This should cut your battle time in half.
2. If your Health is full (or in the white), aim for 2 o'clock.
3. If your health is in Yellow, aim for 9 o'clock
4. If your health is in the red, aim for about 3-4 o'clock.
I'll admit, Warrior of Light isn't the best starting character, cause your Skill and Special are Defensive abilities. So really that tutorial fight, is made for you try out magic and toy with the toy since it's basically impossible to die. Two Earth spells will do the trick.
Once you get the first dungeon, can be tough but you need to mix the balance of Magic and Combat. Don't be afraid to spend all your MP, because there are abilities to get it back.
But if it's not fun for you, then I'm sorry. But I do hope you have a good day!
