My goal here isn't to be an arena PvP monster. I just want to get myself to the point where I've got a decent PvP set for Tol Barad and other battlegrounds.
I'll have a more detailed discussion at a later date. For now, some notes...
A list of craftable cloth armor with resilience, but no spirit (ugh!) for Aeth. Looks like what I'll want is a mix of Emberfire and Fireweave items, trying to prioritize haste > crit > mastery.
Looks like there's no craftable weapons for PvP, though there is a craftable off-hand in the form of inscription's Battle Tome. More research needed here, obviously there's got to be something Aeth can use that won't require Arena play. Myabe?
There's a variety of trinkets purchasable with honor. Same for neck items, cloaks and rings as well. Yay! It looks like there's really only one or two items in each category that fit for a spellcaster, though, so this is less of a decision than what armor set to sport.
Gems are easy to come by, but probably won't factor into her initial set, except for a belt buckle and possible PvE gear gemmed for PvP use, if I have trouble filling a particular slot.
There's a variety of consumables (arcanums, inscriptions, enchantments) that are geared towards PvP. As with trinkets and the like, though, there's really only one obvious choice for a spellcaster in each category.
Or, I guess, I could just Ask Mr. Robot.
For now, I think I'll do my own research and thinking on the subject, and then see what Mr. Robot has to say on the matter.
