Minecraft Name: Sharkykzn
Suggestion: Have spawners that are destroyed in the mining world have the chance of dropping a mob egg related to the type of spawner.
Reason: This would add a unique item drop, which by rarity provides a potential alternative source of income or trade item to the player.
Any Other Information: Currently spawners are used to gain Exp for personal use or to be sold or traded on the market. Currently there are two kinds of player who treat spawners differently, they either farm them for Exp or destroy them to manipulate the Exp price on accumulated stocks of Exp. adding the chance of a mob egg being dropped may add a mutual benefit to both players on top of introducing another means in obtaining mob eggs aside from voting rewards.
Link To This Plugin/Is this a custom addition?: The plugin like Silkspawners could make this suggestion possible, as the percentage chance of a mob egg being dropped when spawner is broken is configurable. http://dev.bukkit.org/bukkit-plugins/silkspawners/

 

So there is a chance at least. ;)
