A nice idea could also be that common items from item mall like bcs, scs, hbs, and even teleportation scrolls could be bought from the shopkeeper. Keep the lucky bags and luxury items on the item mall and consumable stuff like that for gold.
No, put skill vouchers in npc. New playes cant skill with these lag. I fill 2 skill balls per day max. Player who started 2 months ago have all skills max 180 becase they could skill with no lag.
Right now with spam event over there's literally nothing to intice people to buy AG outside spamming bags for pets/top V vouchers or bags for lucky hammer/pestle/ride feed/ipf.... Like do you really want them to take away a staple of the item mall and add the basics to a shop?
MBC+ABC were probably added because you can already get them from the monthly login 5 day streak.
All that buying them from the npc does is save you time waiting.
it is impossible to skill right now. You can't max all skills 180 now with that massive lag. It takes me a couple of days just to fill 2 skill balls (and i use 10 skills to ab skill xP) They can do it for
limited time until the lag is resolved. Could be in green angel instead . Doing mobs is not really affected by the lag spikes much.
