Lightning Bolt is pretty decent as removal #5 that can also go to the face when creature removal is not needed, I wouldn't necessarily call it bad removal.
Other options red gives you include Wear/Tear (which I find generally a little better than Disenchant), Pyroclasm and Sudden Demise.
Mostly Im preferring red right now for the Pyroblasts. With Omnitell the premiere combo deck that is also pretty easy for folks to pick up (as opposed to say ANT), Miracles still the premiere control deck, and with Grixis and BUG big threats (basically, with Dig Through Time decks being all-dominant), Pyroblast is stronger than ever in Legacy.
IMO, the big question shouldn't be do you play Pyroblast, it should be do you play any maindeck (which I think is a meta call; I'd play at least one in any large tournament)?
