That's the same as saying what's the point of damage dealers when healers can go cleric's stance? Even with these changes the healing wouldn't be nearly as effective as an actual healer, a pld whose cure scales off WD and attack power would still only heal for about 1.7k at 60 with i205 (full STR spec), which is around what a level 50 whm cures for, let alone a 60 whm and let alone let alone cure 2 and all their other heals.
