Deathstroke was superior in everything except for regeneration. Deathstroke has dealt with characters greater than Deadpool before and did not have to kill him in order to win, just badly beat him so bad that it would take weeks to regenerate like what happened to Deadpool one time against Hulk. It's also the fact that they completely nerf Deathstroke and composite Deadpool to the point that they bring Dreadpool in, who was not Earth-616 Deadpool, a different universe Deadpool.
