Alright so you kiddies can argue here about it, I'm just here to put some facts up.
[588] <-- Max hit with CR, no boosts.
[640] <-- Max hit with CLS, no boosts.
Damage per hour - based on defense roll in ()
CHAOTIC RAPIER ............ CHAOTIC LONGSWORD
(10) = 432,833 .......... (10) = 377,806
(20) = 428,750 .......... (20) = 374,710
(40) = 420,583 .......... (40) = 368,516
(80) = 404,250 .......... (80) = 356,129
(160) = 371,583 .......... (160) = 331,355
(320) = 306,250 .......... (320) = 281,806
(640) = 182,602 .......... (640) = 183,000
(1,280) = 91,301 .......... (1,280) = 91,500
(9010) = 12,971 .......... (9010) = 12,999
As these statistics show, CR is far superior to the CLS. In almost all areas the CR's DPH is higher than the CLS's and where it isn't, the difference is negligible(less than 400 difference)!!!
