I play everyday with my dad, niece, and nephew for an hour. We play on Whoa!
After creating so many traps, and building up resources we are greatly disappointed to have all our traps be destroyed in 4 hits. This game change may be "realistic" but it greatly takes away from the "fun factor". Realism isn't always fun. We often play games to escape reality, to relax, and have fun. All four of us do not like Traps getting damaged as they now do. Keep the game fun! Don't change what works. Traps are way too hard to build just for them to be so quickly destroyed. Even if traps could take 15 hits on Whoa! It'd at least allow a window of time to repair them.
Thanks for hearing my feedback. Anyone else on the subject feel free to share your feedback as well!
