My opinion 1/2 str/end with 2h sword is both a sucky build and the worst weapon choice for fighter.

REASON : your 2h sword will deal lousy damage while your str won't help with dealing the damage which result in VERY WEAK DAMAGE for a 2h user. U won't have neither the damage of a str neither the defence of an end.

CONCLUSSION : U will be a jack of all trades that excels in nothing.

either go with 1h/shield for tanking or axe for DD.
