I just thought of an extremely good use for the new cave. When the silver update came out, we were think what next, right? So with the pattern, if they update the shrines again, it would mean 50 level 20 dragons. I'm thinking since I have everything done, I start breeding dragons to level 19, place them in the cave and wait for an update. Worse case scenario, shrines don't get updated and I sell all the dragons. If I store 50 panlongs, that's already 4 shrines ready to be upgraded almost instantly, providing I can make the food. Then I can store another 50 of say cold, which is by far the hardest shrine in my opinion, so I can get that shrine out of the way. Then I only have to worry about lightening and plant, which are relatively easy. Any thoughts on this plan?
