大意就是之前有购买新手包的玩家会于5月26号再补送七天的战斗加成
值得注意的是，会直接自行启动，而不是登入以后才会开始计算。
虽说补送很佛，不过这个自行启动满不友善的…
We will soon be granting a free 7-Day Stimpack to players who purchased
the Starter Bundle Pack prior to our patch on May 12, 2015.
These players will start receiving the Stimpack on Tuesday, May 26,
and it will activate as soon as it is granted, independent of the
next time you log in to Heroes. Thank you for your patience, and
we hope you’ll be able to bolster your account progress and gold
collection over the next week.
Thanks!
