In my own multiboxing opinion, I honestly wouldn't know why anybody would keep active subscriptions on all their characters. You REALLY must love to grind (scaled with as many characters you want to gear up). For the gear that matters, this must be done individually. To any future multiboxers, you've been warned: this game requires too many movement mechanics. Plain and simple: don't have high expectations, but if you're willing to do more than the average player, then you may just reap the rewards.
