I started playing only a few days ago and still have about a day's worth of the newbie shield. I concentrated on upgrading my income while only upgrading my town hall if I absolutely had to. Since I'm not spending any money for gems, I currently have two builders.
I'm finding, now, that I'm generating more resources than I can hold and have lost some resources from a collector being full a time or two. Since my 2 builders are constantly upgrading something, it's difficult to sink excess resources into something productive (especially gold).
Since I'm at a level 3 town hall, the laboratory was a huge help for sinking excess elixir. What are the other constructive, builder-less things I could do with excess elixir/gold while preserving my shield?
Note: I'm open to changing tactics if I can more effectively manage the resources I'm generating.
