The 5 element of Chinese are:
Metal,
Wood,
Water,
Fire, and
Earth

IMO air is never supposed to be an important element for Chinese.

For the WOtFE strategy I perfer using them with A/W bless. W9+Double sword combination is well enough to overwhelm most high-defence units, and air shield is also critical because of the best Anti-WOtFE strategy: Arrow.
A high Dominion value is also recommended, that's why I give up F9 and turn to lesser bless like A6/A7.

I once used them in a MP game vs F9W9 vans. Though they had no bless bonus except D4(I am just the sub), they did take down quite some rivals before being flanked.
