For sure, biggest problem i had with 18.4 was not being able to direction while typing in chat. Happy to see this fixed !
For the items, i see the genereal impressions of people : they feel the store might introduce lazy-gaming for richer players ; my opinion is this was already existing by illegal credit and/or PL/OST/Farm/Gear services. So if that money can go to make AO live longer, i'm not against.
Oppositely, the items selling i'm not convinced of yet is the twinkbuffing cans ; i hope the situations where they'll be useable will be under total control (shop/by only, reset @ zoning, etc). Need testing to be 100% sure i'm not definitely against these.
