Hello there, welcome back. I guess you're not an RB yet. I suggest you to continue bursting. You could also train normally if you'd like. If you can't stand training/bursting, you can just RB. Most of my chars RB at level 100 because I'm lazy to burst them to lv180(LOL) JL . So yeah, it's your choice. But my suggestion is that you should burst. Good day XD.
