^^ What he said^^
Seriously they’re not “stealing” the character from you. They have no indication that you want to pick that character. And the only way this would be happening “constantly” would be if you’re playing Alani… which is going to be a constant fight for the next few days/weeks so you should probably just learn that it’s okay to not always get your way.
And if you’re worried about lore progress, then you should DEFINITELY have more than one character you’re working on… probably one in each role… that way, YOU can pick the character that the TEAM needs and be more helpful… you know, instead of just being upset at them, rage quitting, and dragging the team down.
I called myself a filthy tryhard, I know I’m that jerk… but I forgot to reply, there is no my character. If you can’t learn multiple characters, work up your lore on multiple characters, etc. This just isn’t the game for you anyway. It’s a moba. You don’t get dibs unless you’re in a five man premade. And then it’s just fun to pick your character to make you mad
