And Wolverine would one of the cheaper/easier mutants to portray. I know what coconut superpowers are (I contributed to that page on TV Tropes even), and Wolverine's powers are pretty coconut. Boiled down, he's just a guy who fights with bladed weapons, and they're not going to be hurting for cash to show a swordfight.

Also, Arrow isn't grounded in realism for budget concerns, but is a stylistic choice influenced by the Nolan Batman films.
