Is this a bug? 2 hrs 44 minutes speed up with emblem?
Really? Just around 3 hours? I spent almost 2-3 days to donate enough to Lem and all I received was a measly 3 hours of speed up in BL 5?
Is this normal or was I unlucky or what?
That is normal. And emblem is worth 1000 favor (regardless of how much you dumped into it). For a primary. It's less for secondary and even less for the others.
I recommend (1) spending before your get an emblem and (2) use EHSP when donating.
I submitted a report about this, this was the reply from jobynana:
Yes, this is a new feature. Prior to introduction, if you achieved subsequent emblems for a particular giant, they would only allow you to use them daily to increase energy and mood. Thus, the new feature was introduced to make them more of a benefit, should a player mistakenly hit their current favour limit and get an emblem. The speed learning provided by spend is given a limit to encourage potential maximum speed learning by donations as you have discovered.
Yes because Emblems are always worth only 1000 favor points of speed-up, but if your favor limit is say 1400, and you have 1399 favor points, you would not want to hit 1400 and get an Emblem that'll be worth only 1000 favor points in speeding up your skill. Instead you'd want to spend the 1399 favor points, which would save more time on your skill (provided you haven't hit the 50% of remaining time limit).
IIf your cap is 1300. Mine 500 sparkly (really doesn't take that long somewhere like Callopee with Mining 3, without going into Ajaya or Neva Neva). That's 400 favor by itself.
Pop a charge of EHSP, triples the 400 to 1200. Donate. Add a pleasing amber or music box or something, and POW.
The gems you get from that should give you a decent head start on the next game day's donations too.
If you spend before the emblem at the primary giant you can maximize time saved, also you could have been spending every day not just donating. I was saving about 4 hours a day between primary and other giants.
