for my first troop upgrade i opted for barbs. i barch a lot so i figured i could get some value out of them as soon as they're done. i have three days left on barbs, and my dark rax upgrade for witches completes in two days. i have my queen up to 7 currently and have 35,000 DE saved up. should i wait to upgrade witches and immediately get them to level 2 or get my queen to level 8 and farm elixir for bloons as an alternative?
