Sorry but I don't get your point.
To remove the Top-3-Bonus will especially help the smaller or mid-tier-guilds as they will get more rewards, this change will take away rewards from the top-3-guilds and bring it to the guild from place 4 on.

Maybe you don't understand how it works, so let me explain you:

At the moment the rewards are shared into two pots:

• 12% for the Top-3-finished as bonus.
• 88% for all guilds (including the top-3-guilds)

With this this change Crowns and Merrits will be shared:

• 100% for all guilds without any bonus for the top-3

in fact guilds who finish from place 4 to 10 will receive 14% more crowns and merrits than they get now at the expense of the top 3 guilds.
