Will we be seeing the event that the koreans got during which they were given a chance to switch their main class to one of their subs?
Since subclasses were introduced back in c3 a lot of people have played their subclasses more or less as their mains, often leaving the mains behind when it comes to leveling. It is already bad enough that these people in a sense miss out on being able to compete for hero on the class that they play but if suddenly they cannot progress at all on the class that they played since c3 they will loose a lot of purpose in playing the game. For those reasons I greatly hope we will be seeing it and with hellbound drawing closer without any word I am more concerned.
That would be nice to have, even if as a one-time gesture to old players. After all, we deserve benefits for loyalty.
I worry about some of the negative effects, like people choosing their DD subs even if they have tank/healer/buffer mains making the balance of classes even worse-- but Server transfers and name servers always had the potential to cause much more damage. If a person is intent, they're just going to play their sub in place of their main, as you said.
