@Tacet - your numbers don’t seem quite correct to me.
Magic Keys and Gem Keys have very similar drop rates for Legendary, Epic, and UR troops. Gem keys ARE slightly lower - because they have a 20% chance of dropping a traitstone. But those are guaranteed to be runic or better traitstones… so very much worthwhile!
Glory keys have a very low chance of dropping a Legendary troop. But they have a pretty decent chance of dropping other things.
So if ALL you care about is legendaries, then the magic key is very very slightly better. But in terms of overall return, the 3 keys are MUCH more value. You can’t just look at the highest-rarity thing dropped, you really need to consider the full value of everything you get.
If you used 100 magic keys, you’d probably get about
- 6 legendaries
- 25 epics
- 69 UR characters
- 200 Rare characters
If you opened 100 gem keys and 200 glory keys, you’d probably get:
- 5 legendaries
- 18 epics
- 101 UR characters
- 116 rare characters
- 30 major traitstones
- 26 runic traitstones
- 2 arcane / celestial traitstones
I think the extra stuff nicely makes up for the small decrease in legendary & epic characters.
