to start hardcore, rogue might be not be the best choice but you want to go with it, that's fine

you 'll need at least 50-60+ vita to get a nice life at high levels or you'll die

axe : really constant dmg
sword : low and best critics and it can be used on the first classes ( feeder, samy, pala ) but it is also more expensive to buy swords
dagger : constant dmg and you can use it on samy if you pass but it is expensive also
staff : you can use it on rogue only but it is a lot cheaper

. Dmg are between swords and axes.
you'll need around 100-120 dext with gear on (unless you use axes => then for for 60-80 dext then full str )
then all in str

try to keep a good balance between those

str is very important to get constant dmg ^^
EE armor if you go catas ( medium max on rogues

)
Str or dext armor if you go solo ( but hard in HC )
Charms with dext or str again
