But it isn’t essential. I’m just finishing the storages with my single builder the slow way, and it isn’t a problem. If there was any real payoff to doing the farms and mines I would, but the opportunity cost of those upgrades in downtime is huge for only an incremental gain
So I let my second builder lapse ages ago, and haven’t really missed it. In my view the remaining parts of VIP aren’t really worth the expense when you’re in the end game.
Only thing I spend on is Valhalla now, just for the fact that you can get stuff there I don’t have. When you only need two more S1 heroes for the full set (curse you Magni and Vivica) normal summons with high S1 drop rates aren’t worth it. I’m just running one TC20 to try to get those last two - it may take some time
Drop rates on remaining portals aren’t good enough to get my cash, for Atlantis for example I only need the 5s now, only have one, but honestly rates are so slow there is no payoff. If VIP changed your drop rates for heroes or mats (and maybe it should) then I would gladly subscribe
