Supercell just released on Facebook today that they are going to have level 11 walls. This is really cool (even though I am not close to getting them at all). But, with this wall being implemented, I think other wall-related updates should be in the this update or the update after this one.
First, they should decrease the cost of level 6-10 walls. I hear on many threads about people complaining about the cost of walls. I don't really fond of the cost either, so maybe cutting the price back a bit will do us some good. Second, I believe there should be an upgrade row button with the total cost being ready when the row is selected. If Supercell is only capable of doing this with a row of similar level walls, I will accept that, as long as this feature gets implemented. Third, I have found out that there are no walls for Town Hall level 10. It's up to Supercell, but I think there should be 25 walls added to Town Hall level 10. Finally, since we are getting a new higher level wall, I suggest adding a Wall Breaker level 6. Otherwise, the level 11 walls will pretty much be overpowered.
Please leave your feedback on my wall ideas.
