I know, right? It's a matter of prioritizing. Heavy spending ninjas are put into game early, even if they are only for high spenders. Skillbreaks/trials are put in game late, even if they'd be for everyone.

At least skillbreaks/trials are content for the game, once Oasis runs out of ninjas to put in. And we may get few free frags for them in the events, even of we'd have to spend coupons to finish them to full. Unless we're talking about ingot only ninjas, that stay ingot/recharge only...
