L Fizzle, make the bonuses from the events available for purchase! That way those who failed at the events, can buy them! Slap a 500 Gold price tag on them, or put it under the "Add Funds" menu and we can buy it directly with our credit cards. It doesn't matter because you know people will buy them!
There is nothing to lose, only to gain!
**Also, it may calm the after event ruckus in the forums if the players know they can just buy it afterwards.
(EDIT: Something like 500G for bonus alone or 1000G for bonus and unit, however you prefer to sell it.)
Make it happen Fizz!
