Kill3rCombo STARTED OUT good, but they quickly degraded to one of the worst NA kMMO host companies. (Not counting ones like Twelve Foot Tall who hosted Lunia that went under within a year.) It started out as a joint venture between Level Up Games and KOG. Then KOG bought the entire company, which really, explains everything. Just look at Grand Chase's entire history to see how good KOG are at decision making.
-Horribly slow updates compared to all the other major kMMO versions. It took them six months just to get through the Transform 1st Jobs when it only took the korean version 9 weeks. Only now upon Ara's release (Estimated December 4th) are they finally getting within being a year behind the korean version, while Maple Story, Mabinogi (Yes, MABINOGI NA with its small population.), and Vindictus are 4-5 months behind theirs, I believe Dragon Nest is around 8 month behind, etc.
Yet, they tend to rush out hated updates like the Field and Skill Tree Revamp to NA rather quickly. The Skill Tree Revamp was even designed around a level cap (Which shows how horribly designed and thought out it is, but that's a discussion for another time.) that NA didn't even have at the time.
-They're literally the only company stupid enough to keep the Stamina system in place in a NA version kMMO. Everyone else gets rid of theirs for a reason and it is well documented that the korean players have loopholes around the Stamina system such as easy unlimited Stamina Potions and unlimited Stamina and double EXP by playing at a PC cafe. They do however, give unlimited Stamina on weekends and keep on threatening to take it away if the playerbase doesn't vote for them in something. (It's how they got greenlit on Steam. "Get us greenlit and unlimited Stamina weekends will last until the end of the year!") Not even Nexon NA in their scummy days pulled anything involving restricting gameplay and manipulating people like this.
-They inflate the EXP tables for no pineappleing reason whatsoever:
http://elwiki.net/w/Exp_Table
59-60 on NA is only slightly less than what it takes for 69-70 on KR, and KR has stages that give more EXP per run for that level range too. 63-64 on NA (The current level cap, when it was 65 in all the other versions at this point, and thus, there's level 65 requirement equipment dropping that no one can use.....) is the highest listed value period and is more than twice what it takes KR.
Aren't westerners the ones who hate grinding and asians the ones that allegedly like it? Way to be ass backwards KOG..... and combine that with the artificial lengthening that is the Stamina system, and you have a horrible clusterpineapple of artificial lengethening that makes the game not causal friendly at all when the original version is very much so. The recent Skill Tree Revamp made things even worse for some classes by making their core skills have higher level requirements.
-So many big glitches left unfixed. Henrir is the endgame content, but there have been bugs that cause runs to come to an uprupt end, causing one to not get any rewards from it and basically have the run wasted. (And you only get three runs per day, the runs are counted when you start instead of when you get rewarded.) This has been going on for MONTHS now.
-I read something about a recent innocent player banning spree where they wiped the ED of anyone they banned, while infamous hackers have yet to be banned. And at least we know Nexon NA actively goes after the actual hackers. (Remember the Magnus Hard Mode trap? Releasing Magnus Hard Mode before Angelic Buster so he was legitimately impossible? That was brilliant.)
