When all refining mats were consolidated into a single tier, it was supposed to make things more smooth for crafters of all levels.
However, there is a skill requirement of 100 in any refining profession to be able to use the material converters because of the tier they settled on. No longer can we convert excess tannin or solvent into the much needed sandpaper or flux until we hit 100 in the crafting professions that needs those mats. This is especially painful in the grind from about 70-100 for any of the professions because that’s the range you actually start needing to use a lot of refined materials.
Was this an oversight, or is it an intended lever to slow progress of crafting levelling until 100? I hope it’s just an oversight, because the level required to use material converters SHOULD be the same level at which you actually need the refining materials to begin with.
