I hate to say "don't worry about volume," but, don't worry about volume.
(A) A mix's "potential maximum volume" is decided by the entire sum of the core sounds, arrangement, mic and gear selection and technique, recording and mixing levels (if they're too loud, you probably won't wind up with a loud master), the mastering gear and engineer. Anything that falls short along the way will further limit the potential volume. One thing - Is the mix distorted BEFORE the limiter?
(B) Smashing into a limiter (I won't even go into what I think about the L-Series in particular) normally doesn't cut it.
In other words, it needs to be dealt with at the preproduction level.
That being said...
As much as I hate to admit it, I do get an awful lot of projects in that want volume over quality. [Wait - I'ts not a rant, I swear] The key, of course, is to find the compromise - The gear and applications that it will take to squeeze the mix's volume beyond where it wants to be, while attempting to keep the essence of the mix somewhat intact. That's something that varies from mix to mix (no presets), and practical experience is the only shortcut.
A brickwall limiter is normally known as a "quick & dirty" way to increase volume. You're probably hearing the reasoning behind the "dirty" part.
