I want to suggest some things with the 7-Day-Package in Shop -> Packages -> Page 1 -> Long-Lasting Pack.
1.) Make Long-Lasting Super Haste Potion only decrease time when online (like other things inside the package.)
2.) Don't make Long-Lasting HP+MP Steal Potion overwritable with [Newbie] HP steal potion and/or [Newbie] MP steal potion.
2. Is the thing I want to mention ... I overwrote my Long-Lasting HP+MP Steal Potion on a new character named God~Rays accidentally with one newbie thing. Because... missclick AND normally it shouldn't work or there is a popup that asks if you really want to use it again because it's already active.. It didn't popped up so ... directly overwrite. xD
Don't know if there are other things that could/should be changed too.. but both is annoying. xD
