Clubs are great for early dps
If i remember right u reach 65-70 dps under lvl 40 already
Clubs are great if you put a m matrix on them they also take the big damage amps, theyr great for pvp because of the Single damage but when it comes to dpp daggers are the better choice
Shortblades do a low amount of dps in the early stage but increase a lot after lvl 40 , also they are cheaper to buy and offer better dpp but got a very low tt value ( you will need a portable repair tool) also a big - is using a m matrix , because of the high attacks per Minute they tend to eat the m matrix
Longblades are the Mix between Clubs and shortblades
I did runn the castorian Clubs till lvl 45 then swiched to shortblades gained a very good amount of hp after i reached lvl 50 and 200 hp with melee i swiched to pistol
Archon sword offers good dpp and efficiency but the tt value and the durability does not allow you to use the weapon for longer grinds
Same with aakas and corrosive dagger they do perform good but only for lvling
The xeno dagger is the item u want to go for
Hope this culd help you a little
