When I first came to aeria games (via GF) tiered spender events were at most once a month and occasionally skipped a month or two.
since this game went from CB to OB it's been nonstop tiered spender event, after tiered spender event. enough already! if the only promotion tool you have is used excessively, it's effectivness becomes less and less each time you use it. and i seriously doubt the only promotion tool you have is yet another tiered spender event. there's still the misery boxes and (mis)fortune bags you could put on sale or into the ingame mall or the crystal altar...

Some days it's just not worth chewing through the restraints...
