Well, you could easily start by just giving out some crystals, even a small amount for top-5, top-10, whatever, in those others. Gradually make the changes to level it out. If you communicate the change and ease folks into it, you'd still lose some players, but that's the case with a) any change, or b) staying the same.
You have to admit people are going to receive this claim from y'all dubiously. Especially since you rushed in a special buff to ensure spenders couldn't be beat by FTP, telling us JKA was WAI, then nerfing him, and all the rest. You have a rather large credibility problem right now saying this, because your most recent actions make it look like all you care about is those who will spend large amounts of cash, including the "tip of the spear" comment...
Oh there are crystals in other modes, but it's about where the majority of the source comes from.
The JKA thing is interesting to me, we described the change that we ultimately ended up rolling out in the second paragraph of that section of the post, but I've seen people say "oh I didn't think the part about GR meant a restriction" and I do understand why that's so - but that's just a misunderstanding, so we'll think about that when we write the next explanation, but we just can't always convey our meaning.
Just like "tip of the spear" is just an expression to describe the people who get there first, and when I use it, I'm including the nearly 1k people who got Malak without ever spending $1 in this game. There are a lot of people who pride themselves on being completely F2P and still at the frontlines, and they are very much included in that sentiment.
