The grind was huge. I played from 2 weeks after EU launch almost until the very end (3-4 months before shutdown). The biggest problem the game had was the grind for sure. I rerolled 3 times and even when I was a veteran with complete game awareness and how to grind efficiently, it still took me months to become 'competitive'. This skill grind is what lost the majority of the players.The only people left that endured the grind were the hardcore players that played every day. From here, playerauctions killed the game, imo. People started buying reagents, armor, weapons with cash instead of going out and grinding for it. This made the game seem dead as a lot of huge clans never left their cities apart from sieges anymore.
We do not know exactly by how much the we will diminish the returns.But we will approach this issue from the opposite side:With equal player skill, a maxed out character with maxed out gear should beat an average character with average gear 6 times out of 10.We'll then find the proper diminishing return values that ends up creating this kind of winrates.
