If you don`t have a dedicated gropu, yes my dear, you're wasting your life. Try to get a clan and if you cant get parties that way...just create another main and use ur WC as buffer for yourself
Destoyer gets a toogle skill at lvl 40 that improves 2h sword usage. Probably 2hblunt before 40 then 2hsword. But honestly if you dont play solo you dont need a 2h sword, get a spear and a party !!
Please, stop ussing pmfun....is so antiquated...
L2Wiki ( Classic Database) has some nice info...isn`t 100% accurate but is the best you can find out there
