Im a fighter and im wondering what sword is after elven aqua sword the level 45 epic cause i seen many level 60 + with that level 45 sword. Dont you think its too left out and enchanting them its just gettong a +7 bonus. I cant find any other sword that is 50 +

The main reason why people hang on to those swords past level 60 is its water elemental 1 property. There are plenty of other fighter weapons available between level 45 and 60, all possible to upgrade with lapis in order to well outperform the Epic 45 weapon. Check out this list of weapons (current until Ep5) for reference.
