Im TH9 and started level 5 lightning spell in lab yesterday. I used to use it till TH7 to take out one air defence in wars but since th8, it was useless. Now considering the current trends, it seems worthy to zap dark elixir. I see a ton of TH10s with over 3k dark elixir. Boosted spell factory would mean 4 spells ready in just half an hour. Plus i can drop trophies while doing this as well and barch inactives in low leagues. :cool:
