Gotta disagree - and this is from someone approaching 12M GP. I can keep up, but all gold currency goes to kyro's. There's not really any to spare for farming toons you don't have. But, between assault battles, episode currency and refreshes i can typically get enough to get a new toon to relic the week of launch. But, yeah, that leaves other toons that aren't relic'd a bit in the lurch. Same with getting shards for older toons that still need them.
Perhaps the change is throw in a character from time to time that doesn't need them? Or, not every new character needs the minimum of 300. Maybe some just need 100? Needing 300, 400 and 700 is just extreme frankly. It's literally at the point a new toon releases you know its 300. If it's a journey toon it's 4-500. GL 700. That kind of predicatability is boring.
As opposed to variation, NOT having a new toon every 2 weeks would be helpful in that regard. Add to that 4 conquest toons and the journey toons and you're around 30 new characters a year. That's A LOT. All of which require 300 kyro minimum. That's a bare minimum of 9000 kyro's per year to try and stay up to date. THAT is the brutal part. Not so much 300 minimum, but the shear number of new toons per year now.
If you recall there WAS a time CG came out and said they were pulling back on marquees (new toons) because they'd been doing too many and burning people out. At that time they were putting out fewer than they are now. Not sure why it was too much then but more isn't too much now.
