My suggestion, as the title suggests, is to increase the final magic amps reward on Silan, called "Icy Touch" from q40 to q50. Keep every other stat the same, just increase the quality by 10.
I'm suggesting this because nominally, Silan is a 1-50 zone, except for magic, which caps out at 30, because anything you get after 30 is too high level to benefit from the Icy Touch amps. You can't make player-crafted amps to make up for this deficiency either, because the only way you can make q50 amps is with basic mats and the result of using q50 basic amps with level 40 spells is WORSE than using Icy Touch with level 30 spells.
I'd rather see Silan magic cap out at 40 than 30.
