How to improve your current base
I am currently a th 7 runnning in gold league 3
A tip i have for u is to make ur base symmetrical, that way, ur base is defended evenly on all sides
2. keep ur archer towers in the corners so they can pick off squishy tier 1 infantry before it reaches ur walls
3. Have ur mortars centralized and either ur de storage or ur clan castle in the middle. That way, ur de is hard to get to and ur mortars can easily defend the whole of ur base.
4. keep ur th outside, th 7 is a very good farming base lvl, in fact the best, u find the best raids and profit, u shouldnt care about ur trophies that much, at least for me, makking more space in my base for resources is the way to go. Remeber u can also protect ur th with just 2 hidden teslas, and even if u drop 5 or 6 trophies, u will get them back easy peasy
These are my tips on a succesful base, hope it helped
