I don't have a huge amount of time to play each day, about an hour. After my dailies I usually have about a 30-40 minutes to grind. I'm getting to level 7 in about 30 minutes at rev3 without kish as a bucc. So basically I'd need to grind for an hour and a half to max out the event daily. So with only 2 weeks and 20+ coins a day, I'm pretty confident I'm only going to be getting one item.
Honestly, it seems whoever designed the event thinks every player has access to kish or something.
Prices in the shop need to be much more reasonable or the coins need to start dropping from each Halloween mob.
