They’re valuable, but not super valuable to me personally - I have more trainers than I can productively use anyway, and it was even worse at the time when I would sometimes sell Basils at the depot just to clear up enough roster space so I could claim from my training grounds.
I did go for mods over more Benny boxes when given the choice, but they’re also not particularly exciting- I have a good number of mod boxes unopened, because it’s just such a hassle to figure out which mods to sell so that I don’t have to click through that annoying popup every time I play a mission.
Fair point on the FA event; I generally enjoyed FA at the time so I might be biased. The problem with FA is that it is too easy; when it’s not, I think figuring out teams that work well against a particular stage is fun. When you only get to hit with 1* toons so that you don’t deal too much damage it’s no longer fun, though, so maybe it wasn’t the best example.
I have no issue with heavy grinding, because I grind hard anyway. I have a problem with pointless unfun grinding.
@Gravedigger I was doing the event legit as far as I could bring myself to do it (zero point in doing daily SR then, for example), and still had to use the shortcuts a ton. And that’s with playing the game several hours a day.
