Right now I'm town hall seven and most of my walls are level 6. Should i upgrade them all to level 7 before i upgrade to th 8? I also don't a have a barbarian king and i am not sure if i should gem for it because its difficult to get 10,000 dark elixir. I am also probably going max out most of the defenses before i upgrade the town hall. Is this a good idea? Finally, i have enough for upgrading my dark barracks to level 2, are the hogriders worth it???
