Clan Wars: Selecting which Enemy War Base to Attack

Rules of thumbs:

• When the war STARTS .... .... slow.... down.... it's not a race, don't rush, take your time, discuss your strategy and who you're attacking, make sure you've scouted and customized your army before attacking
  
• On the enemy war map you get a "Recommended" target - DO NOT GO HIGHER than this on the list, hit your recommended or lower - but not too low.
  
• If an enemy already has 2+ STARS - DON'T ATTACK THIS ENEMY AGAIN, find a new enemy that hasn't been attacked yet, or has only been 1-starred (the exception is in the last couple of hours of the war when maybe everyone realistic for you to attack has already been 2 starred)
