The key to a happly maple-life and real-life
It's quite simple. It's simply requires a tiny bit of patience.
1) Recognize that MS is a game. A fun, addictive game, but still a non-essential part of life.
2) When possible, log on from 2-n accounts every couple days in your spare time (however many accounts you feel comfortable maintaining)
3) Play whatever character/account you happen to enjoy at the moment in your spare time (while not busy with life, relationships, school, work, etc...)
4) When Nexon has a bit of a 'hiccup', reap the rewards*
*2 is the key. Whether it's an overpowered event like the Time Travelers medal, or a rollback that gives your 10 accounts 10k maple points, by having logged on every so often, you'll end up with an obscene amount of rewards and 2X, 3X, 5X+ events to level whatever up character you happen to be interested in at that time.
Casual gaming and not taking things seriously allows players to participate in every major event without investing an absurd amount of time into any 1 character.
Cheers!
