I always upgrade everything to maximum when playing games. You will get most of the attack power and defenses then. Same apply to Clash of Clans. I am at Town Hall 7 and got all my dark elixir required troops upgraded. Thanks to How to farm dark elixir in Clash of Clans? guide.
Getting everything upgraded is not impossible at TH7. Even on troops upgraded with dark elixir as you can see from screenshots above. You can do so too. Just make sure to protect dark elixir storage well. Else it will be hard…
yea, especially now that you can get the lvl 3 dark elixir drill at th7
