A. Most doesn't mean Mabi should fall into this category as well. There are plenty of qualified people within the game that could easily be better support team. And I don't know where you heard that about mods, but whoever told you that is a liar. In fact, KR literally criminalizes mod writers because it's literally against the recently passed law (the law states that hacking tool used to assist games are punishable. This is largely thanks to big number of people scripting in KR LoL, and yes, Mabi's modding falls under this category). Users aren't punished heavily, but developers are. And the modding witch hunt in NA stems from this.
C. By NA exclusive ones, I meant the items that other servers didn't have the same level of. Fierce Ribbons don't count in this one because other servers got items just as broken as those ribbons. Backbreaking ES and the unattainably high grade guns, on the other hand, are the issues. Giving out more free damages that were meant to be done with in game trials in a server that is already not that populated? Even less competitiveness.
E. It keeps the old players, but doesn't appeal that much for newer players, who are more used to the quicker paced character progression or just game play in general that other games offer currently, as well as lack of definitive class system and lumping the whole combat meta into damage.
2. Fighter actually didn't really outclass melee back in the day because Lances existed, as well as lack of AoE clear from Fighter, usually a Lance Windmill and Crash Shot were good enough. Fighter is in the position it's at currently not because of the dynamic combat patch, but because of its flawed design. Low damage scaling and lack of AoE. It really says a lot when you can reach higher damage with a Gloomy Sunday than a knuckle. Puppets are on the more outdated style as it's really used for utility now since there are better AoE options available.
3. Alban was also a bit of a right direction in my opinion. But for there to be a true Artificial Difficulty, you would need more than rebalancing of skills. For example, handicaps (like 50% max Alban stone). But even then, the game needs more, and that's for devCat to decide.
