Had clanmates struggling with this concept, and it was leading to a lot of 0- and 1-star war attacks, so I threw together a quick video. Using this concept will really aid in making sure you get that 2-star vs TH 9 and TH 10 bases. This is my first ever attack strategy video, so please let me know what you think!
