no, it is the proper use of the word.

Economical Definition: Giving good value or service in relation to the amount of money, time, or effort spent.

a 6-1 is a terrible idea, the stats are worse than a 4-3, you may ass well just save yourself the 2 extra cards and get better stats. 6-7 is a good value for the dorri and feeder enhancement compared to the extra effort of making a 6-11, it is therefore econimical, 6-1 is cheap, not economical.
