I supported a full SPR fighter in Closed Beta to mid 30s before it ended and we never had that problem... probably once or twice every now and then (accidents always happen D: ), but he usually survived pretty well when we grind/king hunting. With scrolls, pots, and a cleric, a fighter should tank alright - just requires a bit more hard work if they're not full END.
No idea about solo-ing though.
The keyword being "supported". Alone he probably wouldn't have been able to do much. And why in the world was he a pure SPR Fighter? Thats like me making a pure STR Mage. @_@
