Yeah, that's hyperbole. I'm picking the best bowler according to my ideal bowling unit, and I don't think my #11's batting is something to consider when doing that. Personal opinion, of course.
Which is why I may take Murali over Warne, but for numbers 8 and 9, and 10 maybe, I think batting is crucial. Given the hyperbolical choice of Warne vs Murali to be consistent, I'll take Warne every day with Imran at 8, Hadlee at 9 and Marshall at 11 after Warne and not before Murali.
I cringe if a team I am supporting has a weak number 8 every single time I see the team list and I like a strong number 9 too. We've all seen or know of many tests where the runs of Pollock, Imran, Hadlee, Warne, Jadeja, Dev, Botham, Streak even Holder (as poor a bowler as he is) et al mattered and made a real difference. Even the tail end fight where the game is the balance. Even Wasim for that matter, a few lusty blows in the first or third innings can totally change the result in the fourth.
A strong 10 is a bonus, but in an ATG side, I'm taking that bonus if the opportunity cost is minimal.
Batting matters for all test cricketers, even when its only their secondary and not primary role. Just look at Nathan Lyon's innings at Adelaide in 2015.

Hazelwood may have been motm, but I distinctly remember Lyon being the one who won it for Australia being him with the bat (and a useful 3 wickets showing with the ball too).
