If you are losing your lane, try at least not die.
If you are facing something like a 
(just examples) and you aren't doing so well against them(got kill early/got poked out/zoned out), try at least not die.
Getting 0 cs and die 0 times is better than trying to get the few cs and result in you dying.
the exp zone is actually quite big, i think it's about half a screen away, not entirely sure.
Yes it will feel a bit boring to just sit in safety and throw out abilities once awhile to try get cs, but watching black and white screen is probably more boring, watching that over and over again is even more boring than that.
Yes you will get behind because you missed plenty of cs, but it will probably just be a difference of a 
and a 
, as long as the enemy didn't get feed out of control(which is accomplished by you not dying) you will eventually get back into the game because you still have all the exp by surviving.
Just my thoughts.
