I vote a 3 for Eden Eternal.
I only returned a week ago, so this mark is probably not as accurate as it could be. I am comparing the game to how it was back when it first released, when I first played for several months.
So in the 7 days i've had the pleasure of playing, these are the issues i've found so far:
1. The same Camera issues that comes up utilizing WASD and the right mouse button that causes the screen view to become wildly erratic for a moment is still around. I notice it is one of the most talked about bugs, and i'm surprised you haven't pushed the developers to fix this, even with what I assume is popular demand.
2. The AP Cash shop is out of control in some areas. I assume your marketing department should be well aware of the purchase ratio of costumes. From a consumer point of view, I must inform you the prices do not match the necessity of the product for the average player. Knowing how service industries work, I can understand the debate about balancing between the need of the consumer and what their willing to spend to satisfy that need, but you've gone above and beyond reasonable.
Why have I identified the costume prices as beyond the pale of reason? Your tier events, the Alpaca Gacha Event, Cross Medals, and the Eternal Altar. They all, some more than others, provide cheap alternatives to your 8, 10, or 15 dollar* costume options. They even provide greater benefits and statistics than your Cash shop ones. Why spend 20 dollars on a quick, white-value costume when you can wait a week for a 20 dollar Alpha, or 25 dollar chance for Prime, and use that 20-25 dollar initial fee (tier event) on more relevant and important materials, moving them towards end game more efficiently AND getting that outfit you aim for (Eventually).
Who are you marketing to with these costumes? It's not going to be towards the person who buys every month or two, they're going to probably aim for game-enhancing features like inventory slots or fortify protections. It's not going to be towards those who spend with far more frequency, as they can sell other cash-shop items and purchase higher versions of a particular costume using in-game currency.
What I am trying to convey is how 20 dollars for a temporary aesthetic, un-beneficial item doesn't seem rationally sound to me. I've never considered, once, purchasing them knowing that I can wait and obtain something far better in the future, for a similar cost. Bring down the price. I suggest making a poll in the Eden Eternal forums to establish a means of communicating with the player base and re-affirming whether I am right or wrong about the price discrepancies.
3. I discovered during the Word Scramble Event on the Diamond Server with [GM]Pizza that there was just one issue that came up. The GM in question conveyed the questions through Announcement Chat, and over the 30 minute event, only briefly mentioned at the beginning who to submit the answer to. A few guild members and I missed that announcement due to very active chat channels during the event, and though we asked who to submit to, we were drowned out over the discussions being made by the ten's of people that showed up. The chat history isn't very long, so evidently, it took a while for myself to learn who it was hosting the event. The details on the website mentioned to arrive at an area, but to locate a GM in that mess of participants is more of an event than what I was supposed to be there for...
As my first event in a while, I was not impressed on the execution. I wonder if it's possible to incorporate event notices into the mail system, or even actually use the Event window for GM events like that. Perhaps if the event is on a timer, have the event window convey warnings or notices (Still think mail is a better option with this, though.) on when it begins/ends.
Thank you for your time. I'll be sure to submit any issues I come up with in later content to Customer Support.
