Actually, the preservation stones, abradants, helped a lot of people to get their gears done. I don't charge and I used those to make my rings or my armors. I wish they'll bring them back (if they do, no Grade B [lol] abradant or Grade A [lol], Enhancement or Deluxe).
AND (a big AND here) no 200 vit stones for weapons (we got the 500 vit costume, I think that's more than enough) or 55% attack, no more 1h pet, or 1 day costumes (big lol here). And if you put holy wine again, make it 5 holy wines not only 1, that's kinda useless. And you guys could put some teardrops in there too (also 5-10, not 1).
Bring back the egyptians, persians 30 days costumes, those were really helpful. Also if you bring Rohanopoly up again make sure to add some old ass costumes (the lunar robes [kinda miss those] or umm, I forgot the names but it was like the ones in the following pictures):
50% has to be taken off IM, and leave 30% as maximum again. Maybe some 24h or 15 days hunter kits, people would farm more that way (in my opinion). No more chicken hat, piggy hat. Beside the fact that they are useless, they are ugly...
Well ok maybe they are funny and a bit cute but I prefer to have them on Item MaII than having them on Rohanopoly wasting slots where we could add something more useful.
If you bring Rohanopoly up again you could put +1 tickets in there (not in the golden key prize, since you guys put golden key hard to get). Put absolute patch / earrings on Golden Key soo everyone can have the possibility to get them.
That's all I can think of at the moment.
Oh, and for god sake, BRING BACK THE BUNNY EARS!!!
