**These guild skills will motivate guild members to level more so I'm all for it!**[/quote]
...Not really. All of them are quite expensive to level up. and they don't last that long, so renewing them can eventually add up. This system is unpopular in KMS as it is not worth the 1.1x exp boost for 30min. It would cost 433,800,000 to get Guild EXP maxed. and 300k every 30minutes.
