Updated tweet link from Holinka.
Titles being more strict can be argued both ways, my only concern is I don't believe there was a single post or announcement regarding a change. Seems irresponsible to ninja change a system that has people putting in hundreds of hours towards as their goal. This seems especially harsh for PvPers trying to get their first R1 or Glad, I can see many of those people would probably just quit the game after this.
This is assuming something new or hidden was used to calculate titles, the wording on that tweet is a bit confusing.
edit: new tweet from holinka says stricter metric is unintentional
