I had notice the purpose of guild is mainly for the following,
1) Daily quest for guild coin ==> to purchase items from merchant
2) Help each other on resources ==> through trade / adventure multiple players buff etc
not really much of on-games interaction in big scale of involvement.
Since there is a change of guild level which is determined by numbers of players, i like to make some recommendations,
1) Guild House
a) Have a Guild Adventure Merchant start with level 0
b) it will required member to build it by donating resources, once enough, GL / AGL to trigger the start building
c) upgrade will required member to donate guild coin to buy architecture drawing, GL / AGL to make to purchase / upgrade
==> might wanna include explorer to be able to search the drawing.
d) Merchant level set from level 1-5
==> Guild level 1 open Merchant level up to 1, guild level 2 for 2-3 and level 3 for 4-5
e) Different level of the merchant offer sales of different guild adventure which allows more players to take part
==> GL / AGL initiate start of Guild Adventure (Duration : suggest 12 hrs or each increase in level of difficulties)
2) Guild Adventure
a) Suggest adventure theme to enable guild member to play in both defensive mode or attacking mode
b) Attacking mode is the traditional / current method of pushing through to the boss and defeat him
c) defending mode is where guild players send / drop resources, troops to defend the goals of the adventure
example, Guild Adventure : Defend the village
adventure start a small village (left side map) with 1000 villagers, 1000 coin, 1000 plunk / stones as walls, 500 recruits is being attack with bandits, the guild is to defeat the boss as well as defend the villages from the right side. Bandits will first attack the the defending army which is the recruits then wall, loot the coins and kill the villagers (last villagers killed, adventure is lost). Attack of bandits is set like every 5 mins, scale of attack depends on numbers camp left, each camp deplete 1 units of the village defends or resources etc.
Guild members can help to defend by adding resources / coin or troops to the village (not more than beginning of the adventure) while sending troops to defeat the boss, adventure complete once boss is defeated
I sincerely hope there is more involvement and game play in guild level
