Patch Available - KMST 1.2.456

That is how they are, untradeable upon equipping. You only need the SoKs after that.

Well that's not quite so bad. Like Polantaris said, if they made everything worthwhile that drops immediately untradeable, it would be time to quit.
Overall though, this update is really sad.
For those who have a level 200, and don't feel like giving in to Nexon's push to start over with new class every few months, what is there left to do?
1- Upgrade equips? Why bother when however much time and money you spend, Nexon does its best to make whatever you get worthless, outclassed, obsolete some months later (as this update does). Plus past a certain point it gets crazy expensive anyway.
2- New quests and events? Collect stuff? OK, but this usually doesn't hold my interest for long. Rewards usually not much anyway -untradeable equips or scrolls which I never seem to use.
3- So left with --Bossing. So with this KMS update, any boss past HT is only doable with a full party of godly players. I'm not that godly, and never will be because too cheap. There may be only a few guilds per server active and godly enough to take on these bosses, and chances are they wouldn't want less-than-godlies like me tagging along , because organizing these runs will be a big deal that they won't do very often, and they will need the maximum firepower they can get to finish in under 30 minutes.
So most of us will be left with only regular Zak and HT. Zak is too easy and since the drop rate nerf almost never drops anything worthwhile. Setting up expedition mules may take more time than it does to kill. HT makes you wait a half hour and still drops nothing of use (once you already have the pendant and card). If these bosses are all that will be left for me, things will get boring rather quickly.
Probably I should just give up when this comes to GMS. The entertainment to effort+expense ratio is rapidly approaching zero.
