--------
Most of above uses elixir so have plenty of gold to be upgrading my walls slowly.
When i went to th9 i was ALMOST MAXED TH8 with only cannons at lv9 and 1 tesla still at lv4 (rest at 6)
i am currently at the stage with the above all built at AQ at lv15 - however i am usually in war matched against a maxed th8 or rushed th9 with new defenses all lower levels. My golems lv4 pekka 3 wizzard 5 (gowipe) easily takes out higher bases.
THIS IS ONLY WHAT I HAVE DONE. THERE IS NO RIGHT / WRONG WAY TO PLAY THE GAME AS LONG AS YOU ARE HAVING FUN.
