There's quite a few players selling dungeon runs for gold and it's causing there to be less players actually doing the dungeons. This is a big problem because these people level up others super fast and these are players who would normally be doing the dungeons with other players like it was originally intended. Rich players who can afford to pay these boosters are usually the people who carry the "less fortunate" through dungeons, and now they do not exist because all of them are getting boosted to save time.
I have managed to find a party for crystal castle only one single time in the past two weeks, and we failed because none of us have our gears enhanced. I'm level 64, and there are only a handful of quests that I can do outside of the ones related to crystal castle currently. Even if I enhanced my gears (already have +10 weapon), I still won't be capable of solo'ing the dungeon, so I'm pretty much screwed unless I pay one of these boosters like everyone else. I don't agree with that, nor do I think it's fair since it defeats the purpose of playing the game.
Boosting others through dungeons for gold shouldn't be allowed. I personally wish the level requirements were taken back down to what they used to be now that the servers have been merged. There are way more players than there was before the merge, and the level limits were only increased back then due to the lack of active players that were in the game. It makes no sense to keep Tower at 70, CC at 90, and LN at 110 anymore. This is only making it more difficult on people who need the dungeon but do not have a million gems laying around to pay someone else to boost them.
