It helps to have a balanced sense of what it is to be destroyed. What you mean by that is to lose your accesible stock of resources and your troops (to be zeroed).
Well, no one likes that but the fact is that an awful lot is NOT destroyed. Your buildings are untouched. Your hero and shaman are still there and have all their skills and equipment. Your knowledge remains.
This is everything you have worked at to develop.
No doubt it will take a while to retrain an army. But troops in the game are totally dispensible. If you are keeping millions (or billions) of troops unused and unhurt you are playing in an extremely dull way.
As for rss, well they can be a bit scarse ar first but later you will have billions and the test is not to acquire them but to find ways to put them to use. And if you join a clan it will happily get you passed the early stage providing as many rss as you can possibly need - it helps the clan for you to develop fast and it is one excellent way to put all that surplus to good use.
