It doesn't sit well with me. It leaves a bad taste in my mouth (Even as I did it myself with this NCB).
Can we please get a change to the whole system to stop us having this method to maximise growth, and literally forcing us into using it.
Like storing up 1600 BA to save for use during Wacky XP time. Or gimping a charcater (like putting a MGS on a high level Mage) to let a mate farm them for massive rewards.
It's not strategy, it's not fun, it's only an allowed exploit.
But I suppose I'm the only one who feels this way. ;)
