Question regarding RDM stats and weapon choice.

[HaroldSaxon]

Spell speed isn’t very worth it for RDM because half of their total casts are instant - and spell speed does nothing to buff those instant casts.

That is incorrect - it reduces the GCD even for dualcast spells

It can also make it difficult to double weave oGCDs. RDMs will get much more mileage out of crit, direct hit and det because these stats apply to all of their spells.

Also, melding strength is not enough of a DPS increase to be worth it.

This is true, although mainly you avoid spellspeed because it doesn't affect OGCD damage or your Melee combo.
