5th level magic items aren't very useful to a 20th level Fighter. Why is this surprising?
At 5th level a rogue has around 44 HP's. Using a 5th level potion he can spend a healing surge to get just one less HP than a surge would provide him. Since healing the rogue is just about *never* a priority for the healers, that potion is pretty darn handy, I'd say levels 1 through 7 or so.
Also something to keep in mind is that whenever the party is hit heavily by AoE's, the healer is not going to be able to keep up by himself very easily, some people will simply have to use second wind and/or potions so they can stick around longer.
And when the healer goes down, someone has to shove a potion down his throat. There is no getting around that one.
I don't know if I'd call healing potions a *must* have, but having a couple in the party is very handy.
