Ruby is in no way going to become a Mary Sue, and what exactly do you mean by bad writing? I said Mary Sue OP powers, though Ruby does have high potential to become a Canon Sue. I mean, seriously, out of nowhere Ruby turns out to be a descendant of a line of god-like warriors that can KO a Maiden at full strength (read: A physical goddess), and a powerful Grimm in a flash. That's the kind of bullshit I'd see in FF.net.

Deus Ex Machinas are always, always, always bad writing. They consist of when a situation is unsolvable or hopeless, then suddenly and/or unexpectedly, a solution appears out of nowhere with either very weak hints or no hints at all leading to it, that solves the situation.

They are always bad writing. The question is when are they acceptable. Some level of bullshit is acceptable if it's runs on Rule of Cool or Funny among other things. Not in this case, as it didn't really run on any rules.
