I don't find Riposte useless for a locker rogue. If you are first to gain aggro, then Riposte is actually a great skill for locking. Imo I'd go 2-1-1 dex-str-vit and use Shadowstrike, Quickstrike, Riposte, Lifesteal, Poison Weapon, and throw any extra points into Fast Reflexes. For gear, Shadowstrike Hrungnir helms, Occult pants and boots, mixed with dl/edl have been very effective for lockers on my server, but I prefer to wear full dl so that I don't die as easily when I gain aggro. You want dl dagger and rondel ofc but there are many great options for weapons at your level. For jewelry, IMO I love the Wyldshrine Amulet of the Sun(Can't turn down a pierce dmg skill), the highest tier Silverweb Charm of Night you can get your hands on, 2 Shadowstrike Renegade rings, 2 Paradai or Osan Quickstrike/Riposte rings, and for bracers You can go for ones that add skill points or you can use Wyldshrine bracers which I prefer. Wolf Battlemount for the pierce dmg skill and a Poison Dragon if obtainable. Happy Hunting!
