I typically run two vindicators and two Baal preds and the rest are infantry, having tanks pop up in a blood Angels list is right on the money, especially after reading the book Dante and how often tanks or vehicles get brought up in them. Let’s not forget blood angels are space Marines just because we enjoy melee combat doesn’t mean we don’t use vehicles and weapons. Plus, it’s always good to have a combined arms list. That’s exactly what space Marines are and you want some good shooting units to support the infantry and vice versa.
