The guild and guild wars is whats keeping this game alive so it will be the focus of this construct
Generally the lifespan of card battle games is no more than a year. To keep the game running after that require significant change which usually comes in the form of placing everything behind IAPs. This game is nearing its 1 year lifespan and we all can see that it is slowly dying hence why we are seeing these constant changes good or bad.
Here are some suggestions
* Abolish ranking system (save for leader and vice)
The purpose of a guild is for a group of people to come and work together to better themselves which in turn improves the guild.
This has been a subject to scrutiny many times over but I think I can propose a better alternative
The alternative is a system wherein the leader sets certain parameters for members to aim for and once reached they will receive that particular benefit.
These benefits of course will be the buffs you get from guild lab.
Each level of benefits will have it own parameters for members to reach
For example a leader can set a parameter for obtaining 5% HP increase in battles by donating 10 million coins. Likewise a 10% HP increase would require a donation of 20+ million coins.
This will create an even playing field for all members where everyone has the chance to obtain maximum buffs
* Changing guild name and banner
Leader can change guild name and banner at the cost of coins (insane amount) or gems (low amount)
The required amount will increase every time this action is taken.
This is just to add a little fun to guild building.
* A 6* card after reaching lvl 180
Quick note: It adds 20k exp per level past 150.
The new increase in lvl cap certainly breaths new purpose into playing the game again with the desire to reach max lvl once more but to give a much heavier meaning into this endeavor I suggest we get a 6* card from it. This will provide greater incentive other than your normal energy and CP increase.
People will spend a great amount of their time [and money] to reach 180 generating more and more activity within the game.
