There is a bug related to Reave that can cause it to sometimes not hit targets that it should. This has been fixed locally and should hopefully be deployed with the next patch to go out.

" Odoakar Yeah, my lvl 63 CI crit reaver has around 89% chance to hit, but more often than not you would see reave effect hitting the mob but not doing any damage.

It is worth mentioning that the on-hit particle effect is client-side only, and shouldn't really be used as a reliable indication of what enemies you are hitting (for example, particle effects will still play on enemies that are out of sync and not actually in range of the attack).
