Rapid shot is good but you don't really need to put much points into it. The 10 seconds of rapid and light heal is better than just rapid in my opinion. Perhaps get a ring that gives skill points for rapid.
I recently bought 100 Rimebound chests for 4000 platinum when I meant to purchase 100 Aeon chests. I was hoping I could get them exchanged. I sent an ingame support a few days ago and haven't got any responses
