That was when we were talking about other healers and beyond the war.

Even you listed bandages and etc. that saved people's lives or patched them up before the introduction of Wendy. Even doctors and still Porlyusica can save them in Wendy's absence. I am not even going to count the poison to Erza since I am strongly confident that poison is just make her suffer for a long time before dying, just for Wendy to arrive just right before it was too late was pure luck. Even with Lucy's wounds from the GMG were serious yes but not enough to be near fatal which didn't kill her almost immediately that provided enough time for Wendy and Chelia time.

But I will digress from all other points and since we are done talking about the past, then let us stick with the present.

Once again, the battlefield is in chaos with no front or rear lines, it is just who ever is near will battle each other. Well Alvarez is an exception because of their overwhelming numbers
