Yes, this would be a choice once I've gathered everything. I didn't grab Blackened Plate until level 16, and I don't think I can at least post level 13 at the earliest (but even that's doubtful). What enabled me to kill the Fampyrs painlessly was to spam scroll nukes by multiple characters, and I can't reach high enough Arcana for a while.
In contrast, I grabbed Patinated Plate at level 8, so it is the default armor for a long time.
Ironically, it's the very speed advantage that Patinated Plate gives that makes me not like it as much! (Of course, I can opt to avoid the speed enchant though.) With the speed enchant (and bonuses from MC Berath's Blessings, Alchemical Guile, and Swift Flurry), I was going ahead of the main tank, and I definitely didn't want to do that. Instead, I like to set things up with my main tank (Swashbuckler) putting Persistent Distraction and Lower Their Guard on multiple mobs and enabling my MC to do massive damage with Clear out>
