大意就是之前有購買新手包的玩家會於5月26號再補送七天的戰鬥加成
值得注意的是，會直接自行啟動，而不是登入以後才會開始計算。
雖說補送很佛，不過這個自行啟動滿不友善的…
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!
