Clash of Clash 2016 Update Request

Hello players of Clash of Clans and Developers of Clash of Clans (hopefully) I was really putting some thought into this and thought it would be really cool to add into Clash of Clans, hopefully sometime in 2016. I will continue to list all my Ideas in here, if you see this idea already somewhere please let me know because I did not intend to steal anyone's ideas.

-Spiked walls (Does damage to any troops that go over the wall, usually used as a anti-jump spell defense or hog riders)

-Some kind of enemy with the ability to go underground to avoid damage (must pop out to attack a building and have about 30 health)

I was looking for an update with the lab. I am yet to up my lab to level 7 but i want to plsn troop and spell upgrades in advsnce, but i can't even see the detsils for the troop after upgrade without upgrading my lsb. Pls change this so that we can see the cost and details for a troop/spell just like you can see for a maxed out object for that town hall level but the window says you need to upgrade townhall to level n. Pls make this change in the lab.
