WotV has a lot of monthly rewards for doing certain tasks x times per month. I wanted to make a checklist so I didn't have to constantly check the missions but figured I'd also check to see what my daily targets need to be to hit the month total.

Most notable, assuming you'll be running missions with the better rewards, you're going to spend on average 272 energy per day on these dailies. At 480 free energy per day (we also seem to get a decent amount of energy pots) that's more than half of our energy going towards day. If you're only using 16 hours of energy per day that's only 320 energy available to you so you only have about 50 energy to spend towards events which is nowhere near enough to get all the good rewards. You can get another 90 energy by watching video ads (similar ads to the FFBE ad wheel)

On the bright side, most of this is just annoying resource wasting. The game's auto battles makes it less time intensive (but in no way casual) although you need to check your phone quite often. The skip tickets which allow you to automatically clear story missions that you've already completed and still get the credit and rewards takes a lot of the annoyance out.

But this is the grind just for the month rewards. There's a shitload more to do just to make progress on your units. And while you could just ignore the monthly quests, they appear to be one of the main sources of very rare resources (rainbow fragments which is the biggest bottleneck for unit leveling).

tl;dr: You've probably heard that WotV is extremely grindy. It is. This game is NOT casual friendly by any stretch of the imagination.
