Ironically I did! Not to mention I was one of those noob warriors getting ks-ed by assasins and I/L mages and what not, be it in HHG1 or MP3/GS whatsoever. That's why i'm so thankful that mapowner rules exists. If more than 20 people (implying 1 person 1 character) are here to compete on popular maps, of course its a first-come-first-serve basis, what's there to really complain about. But is that the same for royals? Problem is, in royals where multiclienting is allowed and encouraged, some people take it too far and hold way too many maps, leaving almost nothing for players who don't multiclient. Is it healthy that this game allows 1 player to hog most of the resources in a map with several channels that is meant for multiple players to share and use? I personally don't think so.
There were more kids and immature people playing the original maplestory than real adults. Just because it happened in the original game, shouldn't mean we should do the same exact thing on royals. Most of us are adult people with careers, families, etc. I think, things as multiclienting or making a trade offer can be reasonned with kindness. I always believed in that the point of the community, is to make the experience enjoyable and memorable to every royallers of this game, not being a selfish asshole to the others because your entertainement matters more than the others. It still shouldn't be encouraged if it comes to a point where players have to wait a good amount of time just for a single spot to liberate.
