yes, you are.
100%
bullseye doesn’t even really need duped
Take the new champ, especially when those are your two options. Gems will only become more prevalent.
Meh. Its up to you how you wanna run your account.
Personally, im collector so if a champ cant be gotten froma basic 7* or Titan crystal, Im going to snag them and focus my AGs on them.
But some people like to focus on favorite champs to play, or favorite characters from the comics, etc.
BUT ..... im also a silver star snob. If I have a champ I love playing I want that dupe even if it's pointless, ie; BWCV. She may have the most pointless dupe in the game but since she is one of my favorites to play and I cant dupe her from a crystal, I might use an AG on her before someone who benefits from it more.
In the end just do what makes you happy to play the game.
