1.palladin healer + some damage and skills that could save all party members like mass shackle etc...
2. bd with fury dance

3. tyrant + fury dance = insane killing mashine seed is just horifying

you see pala would heal the party and tank the mobs while dd use dances and tyrant would be main damage and hes good speed + good critical rate , then pally would do angelic icon + fury dance + swith attack potion = about 1.5k p.def + atck speed about 850 ( imagen wearing dagger or wists) + he would get bonus in ayack power (dont know corect bonus) and so on ..... alot of fun for every party player

for me the best fighter party is this
1 sk
1 pr
1 wc ) with or without cov
sk hex pr shoots wc buffs and eventually heals
you can add an extra archer either a pr or he

SK/DA, some archer, prophet or WC

orrrr

SK, SH, SE < de party xD

orrr

Some summoner (warlock maybe?), pp/WC, BD

se,bd,sh =pwnin combination
wc,wl,wl=same
