I had been playing Heathstone again a lot, but the grind finally caught up with me right before this launched lol. Plus I was running out of space on my phone, so I decided to skip it, for now. I have plenty of gold to buy packs (I had been saving for this), and I look forward to playing it again at some point :)
Right. I saved for 35 packs and opened them the other night. It all felt quite underwhelming and I’m not sure I’ll okay much of the new expansion. Well when the single player content drops I will but I don’t plan on making a Boomsday deck right now.
