Have a Shield of the Crusher prepatch, and a Sword of the Valiant Warrior prepatch that I was able to use since I was 38th level (allowing me to carve up the lower level mobs like butter). I've carried it around for forever and have an azure rank 6 and a normal plaguefire enchantment on it.
I've been eyeing the grand knight set for a while, especially the sword which has increased damage with some significant defensive bonuses. Problem is, I'll sacrifice power, arpen, AND crit if I give up my current set, for more defense and recovery. Plus I'll be stuck trying to farm to get another plaguefire.
Any thoughts on whether the switch will be worth it, or should I stick with what I have until I finally get a Timeless sword (in like 50 years... )?
