Only thing I can think of doing is +5dex-5con. Would do +4wit(that's cast speed right?)-4int but someone told me that attack speed determines how fast I sing, not cast speed. And getting +4str-4 con with the dex seems like it would have to great of a hit on my HP. But, I'm not sure, that's why I'm asking ;)
Personally I believe LE fighters were made balanced out and should stay balanced out, however since they start out balanced people can pick a DD setup or a tank set up, just that if will never be on the same level as TRUE DD or TRUE tanks. If you plan on going offensive then make sure you go all the way. In other words don't go +STR and -CON and then use defensive armor and shield. In PvP the ONLY DD setup that works well for SwS is +STR-CON, Blue Wolf/Majestic heavy with a Bow. However if you like to melee in PvP as a SwS -CON is a terrible idea, other enemy melee will see you as a vulnerable target and jump on you.
Personally I go for a defensive/balanced set up, I have no tats anymore except +WIT/-INT tat. That tat should be used by ALL SwS. The ONLY skill we have that uses INT as far as I know is Entangle, and quite honestly its lvl and using a Blessed SpS determines whether it lands or not more than your Matk. WIT not only raises cast speed but also is your resistance to curse spells and things like sleep/root/para/etc. Being as LE are balanced magic and physical stat-wise their WIT when tatooed can reach that of a DE MYSTIC without tatoo.
