I agree with this.
I truly think ANY character can become high profile given they have a great writer with a genuine interest and love for the character & cast they're writing about.
Think what they COULD have done with Ted Kord had DC decided not to go all 'killy'. That single issue (Countdown to Infinite Crisis) generated a TON of reader interest that could have easily been channeled into giving Blue Beetle the push he deserves. Jaime is a great character, and I've supported the book from the get-go, but I do think poor old Ted got well & truly shafted.
