What he said ^. If you find freezing fun then do it, if youre getting bored then level up to 80, get a new SWB and fight those guys, even though you're still gonna destroy them. I recommend going up to lvl 85 if you wanna fight, some freezers at 85 are sitting at 90k+ power so youll find a challenge there. Also , nice Madara, thats daddy right there
