The only reason that the XBow costs are 30 million total is because the player is assumed to have constructed 2 level 3 X-Bows at TH9.

The cost would be 2*(3M+5M+7M) = 30M.

Boom Beach has shorter upgrade times, but IMO is nowhere near as popular as CR or even CoC. You are given long upgrade times, but you do have multiple builders, as well as many other defenses to hold on to while the upgrade is going on. In the end, it's a permanent benefit to your base.

As for CR, well, even though upgrading is instant, how long would it take for you to accumulate the cards needed for the level up? Unlike CoC, you can't simply gem the missing cards, you know.
