I understand that you want to provide a variety of buffs to compensate all classes and events but I believe Marketplace, Scout, Library, Hunter, Treasury and Mercenary also should be permanent buffs. I know that 97% of the game is Turkish and playing at the same time zone but for internationals like us, all of these buffs are pointless. If the plan is to launch this game to global scene, clans should provide these permanent otherwise all international players would prefer not to invest in clan but their own characters.
There is no cosmetic we get, no real benefit, why would they even want to pay a dime in this regard?
This could potentially kill clan loyalty because some of the players will never be able to see these buffs are actually amount anything for them.
For our case, we have people from 7 different time zones. I cant get all my clan members at my time zone to use buffs.
However, dex-str-mp bonusses are usefull to use in pvp where we agreed on a specific time and act on it can be used in clan vs clans, invades(if ever gets released), events.
With these current buffs, and how hard to upgrade and obtain them. There is not a single point that promotes loyalty to the clan. Monetizing or min-maxing can be implemented way more better than this from what I know about you and what you are trying to provide.
Eventhough it looks really good on paper this does not provide any benefits if those buffs are for only 2 hours.
Why would someone spend hours of gathering then investing in to someone else's clan, then hope to be active at a time that buffs will be on?
I might understand for stat buffs as I said. I like the idea to have them on cooldown and 2 hours is a valid time period, but the rest isn't even worth getting excited for. Individuals wont be able to get any benefit until the clan is really high level and heavily invested on. So why would they bother while they can purchase xp scrolls that already gives more buff and even way more cheaper to get?
The game should be easy to play, but hard to master. Not the other way around.
