I understand that we will be receiving HB in tandem with Gem purchases but I'm still unaware if it was confirmed that gem purchases prior to the update will give HB.
I believe so, if what I read somewhere else is correct all those who purchased gems before will get their corresponding free HB also.
Getting free HB is one thing (and sure helps a lot), but gaining the required EXP to level-up heroes isn't too easy especially when you get to Level 80+ where each level requires 10k+ EXP.
He actually said when the new update comes out they won't be giving HB at all when purchasing gems. Then he told me that he couldn't give players any info regarding the update, so he kind of confused me
