I tried finding an answer but couldn't. Sorry if it has already been answered. I've three questions: once I unlock that character with 100 favor points, will the level 2400 characters stay the same price (175 FPs) or will they subtract what I've paid for the level 100 character? Are they worth buying? Considering the price and benefits of buying them. And finally, suppose I am level 4360, never bought any characters and go straight to buy the tier 4 character, would the stats be the same as buying one by one or are the characters benefits stackable? Sorry if I wasn't clear on my questions.
