From what I can tell the worst of the "bad word of mouth" was around launch largely from people who either didn't play the game at all, or just played the trial briefly then hopped into the dogpile.
Word of mouth outside of that, while not exactly great, doesn't seem nearly so bad, and outside of a handful of masochists, most people who sank dozens of hours into the game seem to like it, both here and elsewhere.
When they fix some quality of life issues and bugs, and drop the price, a lot more people will likely take the plunge, and enjoy themselves. Comparing it with Destiny is apples and oranges, but I think yes, it'll be remembered far more fondly than the launch window gif circlejerk would imply.
