The lightning comes from the wizard Shazam. Surfer could use telepathy and predict the lightning. He'd have no problem dodging it, since lightning only travels at about 40% lightspeed, and Surfer's beyond lightspeed.
Who has Surfer fought, in a dire situation, while bloodlusted, and has had the option of turning them to stone, and didn't? Mad Thor isn't a good example. Surfer certainly wasn't bloodlusted, and Thor's got a lot to answer with. Simply because he hasn't used the ability in certain situations doesn't mean that he doesn't possess it. That's the purpose of the vs forum. In a comic book, it's the writer's call. On this board, anything goes.
Stan Lee intended the Silver Surfer to be every bit as powerful as he is portrayed at his best. Surfer has used his power to transmute his opponents matter more than once, and he has done so pretty recently. This isn't like Thor stopping time. Such an ability can't be simply dismissed.
