My god what is your problem @Zakkhar? Firstly, this is a new user experience feedback forum, I'm telling you about the experience of a new user, which you clearly are not. Right now, the experience for new users is poor. It is not clear when you're spending platinum on weapon slots, or that weapon slots are even a thing in this game as a new user. What I want is better UI design to make it obvious that weapon slots are a thing, that they cost platinum, and that you are spending platinum to open them. As I said, not myself, nor my wife, or literally dozens of other examples I found online with a simple google search who all had this problem, saw any sort of prompt, confirmation, or warning that the action they were taking was about to cost them 12 platinum. What I want is for them to make that clearer, why would that ever be a bad thing?
And why would you want users to have to contact support to find out what they spent their premium currency on? It's a simple feature to add which adds a lot of value, takes the burden off of support who shouldn't have to look through my history to find what I purchased, and leaves a poor user experience. That's also bad design.
And finally, your comment of "And? What me or any other player reading this has anything to do with it? You do not like a service, you do not use it. This is not google review." is so god damned pointless. The reason it matters is that I'm a new player, potential revenue for the devs. This forum exists for user feedback FOR THE DEVS. I am saying that I am less likely to give the devs money because of this experience, therefore, it's important feedback to give them.
Your comments are pointless, miss the entire purpose of this forum, and are needlessly hostile to new users. Be better.
