Personally I build fighters without any END at all. They simply suck and die in guild wars.
Ps even without END you can tank effectively with good equipments. One thing I do is to switch my weapons during grinding (could be bothersome if you don't like it). But I have my shield/1h and axe hotkeyed so I devastate with axe and switch to 1h and shield when its about to wear off, and I just switch back to axe once devastate is about to be ready again. As for 1v1 against others I cheap by switching to 1h and 2h and using slice and power hit in succession.
