Farm Leaves OR buy Leaves?

Coins are super easy to farm outside of exchanging leaves. There's the board games, doing 3 PQ/mpark and such, raising tree pot, opening town boxes. Also you have like the whole month left for this. I honestly don't understand why people would waste so much meso to buy leaves, I guess they are just way too lazy.

The problem is that my main account already used up those clean slates. I honestly don't have many mules lower level to use it on. What level would you recommend so I can get those coins fast on that character?

The boardgame churns out coins pretty fast. As someone said above, don't really need the leaves lol. If only mine weren't glitched

So what level/class would you recommend me to use the board game if my main account already got 5 slates? Also, how long does it take to get 75 coins from there? What's that glitch though?

100 leaves = 1 coin
15 coins = 1 clean slate
One out of five clean slates should work so for the sake of argument, 5 clean slates = 1 White Scroll.
5 clean slate per character so you need 75 coins or 7500 leaves.
7500 leaves * 15000 meso (being really really generous here) = 112,500,000 meso / white scroll

Current NX Ratio = 1k : 65-70 mil
Shield Scroll costs 2.8k NX
This means it would cost 182 mil on the lower side to buy 1 Shield Scroll.

5 Clean Slates cost 112.5 mil.

MATH!

Leaves are like 10k each. I'm not sure about using Shield scrolls because they seem a bit costly, but should I really stick with them like after I clean up all my slots? Or just keep using slates?
