Go less off focused...and pump harder. try pumping on 50% homes, then swap down to 30% once trained. at 30% homes we can compare feary v elf for example and u'll get a 1100 acre elf has the nearly the same numbers of wpa/tpa/def and total nw as a 1000 acre feary. So the advantage of elf would be High wpa 'faster' since u need less "Raw" wpa. I'd go 50% homes to get 30*1.15*1.02=35.19 ....6 tpa 6 wpa 3 epa. Then train as much def as u can to say 12.5 dspec 7.69 ppa. Very reasonable to train to. then swap down to 20% homes and u lose 3*1.15*1.02=3.519 ppa, and boom your on like 4 ppa and insanely trained.
at 6 raw tpa, u should be able to sustain yoru military stealing till war, and enter war down to maybe 5.5 raw tpa+low ppa
