I've picked the game just recently and I love it so far. I like it how you usually have to think up before acting. I'm glad to see it didn't change much since the older games - I've played some, though it was many, many years ago...
However, I have to admit I'm constantly running out of orbs. And the summons... Well, I usually get only ones I already have and the best are 4-stars. I want some 5-stars too
I agree Lyn is the best
I've picked her up just because I remember her from her game and I liked her, but she's so insanely powerful... When she attacks of course, she can be quite easily killed in a close distance. But she can also move over a long distance, so it's easy to play with her.
I think I've also seen a sword Lyn, without a horse. She didn't seem so powerful anymore...
