Hi,
I would suggest that no more buffs be provided in voucher codes. Instead provide some coins or gems.
There are hosts of low level players for whom coins make more sense especially when they think of upgrading their buildings or buying stuff from the market. Also, we have seen a deflationary economy in this game - things getting cheaper day by day (in terms of coins).
Quite like global economy with money tightening facing deflation. For a change, how about we see some ease in money supply and lets see how that turns out for the game economy and the players. I bet players stocked up with stuff would also love to sell it out with low level players having more coins in hand to buy.
So please for a change don't give buffs etc (at-least for the next 2 - 3 voucher codes). Some coins would be a whole lot better for everyone in game. Maybe 500 - 1500 coins in the next few vouchers.
