If daymaster is strong than don't need resource
Not as simple as that. You need resource and wealth if you use officer in stem. Together, they can form a high level structure.
You don't need resource if you use weak HO to produce wealth. You don't need resource and wealth if you use EG to control 7K.
Besse and Fox died during fire LP.
Besse got murdered in November 1986 and Fox died from cancer in 1975. Both of them deal with strong 7K in this period. EG can't control 7K effectively due to fire LP which favors 7K earth.
You will have the same problem during fire LP, therefore you need resource to protect water from strong wealth and 7K.
Just like everyone else, your chart isn't good enough to function alone without a partnership with other charts.
