Theoretically the cost saving on upgrades and cheap healing for mass , are astronomical. And from a balance prospective and in line with delhi meta it requires prep/early investment.
Now the question is:
“Can you survive or even thrive long enough to have 10 scholars and be in castle?”
I believe this is even more so the question to answer when NOT going TOV and considering the ghazi nerf.
Likewise because of the ghazi feudal nerf i still do not believe in the delhi 2TC option.
I think DOF play is tower/DOFscholars FC or sacred sites semi FC. The latter offers at least 125 bonus gold per site you capture (decap takes 60s).
To make 9 scholars from DOF you need 4.5min of production and be able to diverting 130g/min (~3 WB vils on gold or about 1 sacred site) toward said production. That investment is tiny!!! 585 gold?!! Relic captures aside (lulz), 10 total scholars (the 9 made plus the 1 free), allows all your non unit veterancy upgrades to come in less than 2.5mins, meanwhile all your unit veterancies take less than 75s?!!! AT some point you’re bound to have at least 2 Blacksmiths so effectively all non eco castle upgrades will take an effective 75s or less?!! All for 585 Gold?!!!
IT’S even better than described if you have the APM to micro the scholars in and out of facilities to maximize efficiencies.
Again the numbers are insane, BUT can we survive that long without TOV???
LET’S FIND OUT!!
