This is the common wisdom, certainly 2 and 4 is better than not working with the metronome. I used to interface with the hi hat as well. When I started to play Alvin Fielder, I really started to hone in on the ride. With certain drummers, the ride will give you the information for each beat. With Alvin, we were very often moving in and out of a straight quarter note swing. When I got to play with East Coast drummers with great swing, we were still playing more abstractly, but when time came up, I found it in the ride.
A couple of my teachers told me to make the metronome swing!

In the words of Dwight Schrute - "False!" It is not "...incorrect."
Those of us who play a lot of quarter-note based walking basslines find that using a metronome on "2 & 4" can be a valuable tool for emulating the drummer's High Hat on 2 & 4 - NOT to accent 2 & 4, but to practice hearing the HH as (one of many) reference points....including the "count-off" at the beginning of a tune. (Esp. with new students of 4/4 based musics.)
And, finding other metronome settings (other than on "all four beats...."), can be very useful as well - for example: beat "4" only, or beat "2" only, can really check your inner-clock vis-a-vis how well you hear, adapt to, & embrace the aggregate "time" in your immediate surroundings.
"All 4 beats.." is like someone still using training wheels on a bike while claiming - "Sure! I can ride a 2 wheeler!".
IMFO, of course, as always.
Thanks.
