With how long that took I still think it's a stretch that Gray was originally put into the final team even before Natsu had to leave to save Lucy.
But guess it shows was pure stubbornness can do for you
. Really the only strategy to use was to pretty much tank hits and get in close enough to one-shot Rufus. Luckily Rufus wasn't nearly as durable as Gray or this fight could have taken a long time to conclude.
Wasn't bad either to try and just overwhelm the memory make by shear numbers.
Good laughs with the other group though. Heck of a strategy there Happy
. Even had Yukino smiling a bit.
