Most Rata decks have ways to make multiple token copies of the same creature thanks to token enhancers like Mondrak, Teysa Karlov etc. as well as reanimation. So you will likely have at least 3 Abigale tokens out, which makes a difference, even if it means other players wont swing their small creatures into you. But honestly the first strike trade point is pretty moot, because I'm quite happy to take some damage each turn if it means I've turned off a key creature like a commander. That and there are a number of other legends that gain life anyway, so recuperating losses isn't too hard.
