I'm gonna sound trite here: you have two questions to answer for yourself before switching build because a build is a mean to an end. 1. What type of play do you enjoy most? This is likely the most important one. 2. What is you goal in game? Those two will dictate what you do. I was basically a HLBC Hansel (before HF came out) but switched to what you see now. Honestly, I get less gold but I do well in PvP events being a bit spy heavy for my level. I need more towers before I subject people to warring with them again. HOWEVER I do miss Hansel style KaW so I probably would not change to atk build now, knowing what I know. Not that this build is bad. It actually suits my goals for the game - it's just not as much fun for me. Hope this helps
Level 1 stable is the best building in kaw! Provides so many options and kaw mechs are messed up so its overpowered for the fun of winning against far bigger def than it should.
