Thats totally fine too, it’s just that energy could’ve been dedicated to other cards where there isn’t an issue. I also power through some of these occasionally if I don’t feel like busting out pen and paper, etc.

Yeah this is an issue. Particularly if you keep periodically doing Anki, with just enough time to have lapses. So I set Anki to mark leeches instead of suspending them, and when I go through suspended / leech cards I do an assessment.
Nope! It doesn't work that way; each card is scheduled independently of others. You're not going to see other cards less due to seeing one card more.
Busting through leeches just adds to the workload; you still spend all the same time on the other cards.
(Even if you set daily limits on reviews, that just causes a backlog.)
I have found in the past that
(1) with sheer persistence, I busted through leeches. For instance 催促 used to be a leech, in a deck of cards where that is the front. Now I know the word so well I can recall it in the reverse direction: for instance to talk about how it used to be a leech. :)
(2) given enough time, cards you know well will turn into leeches, simply due to occasional gaffes. The conversion of a card to leech is based on an absolute count of how many times you got it wrong, ever, regardless of how many times in between you got it right.
