The title says it all. I will seriously consider quitting for good if raid boss health further increase or remain the same as the last one. I've been playing this game before Gree took over and I've spend quite a significant amount on this game in total. It just doesn't make sense to spend on something I no longer enjoy.
If the health is reasonable, I don't mind spending some golds to finish it up and I pretty sure many player have the same mind set with me. Think of it in marketing sense, if many player buy 110 gold, it would certainly be much profitable instead of a few player buying vault, it would be much more profitable then having only a few buying vault. Please rethink your strategy.
