General Thoughts
I've played scholar essentially since A1 and I've enjoyed its various iterations. Generally I think the exp gain is relatively well balanced for medium to large groups (with 2-4 dedicated scholars) and recent changes mean that solo/small group scholars can make money both from quests and the market.
My only real pet peeve with the profession has been the really large effort crafts and weird exp skew toward parchment. The large craft issue has gotten worse with the active vs passive stamina regen change and the parchment skew is both better and worse for the addition of the Svim quests (T1-T3 bark/parchment disappears so quickly...).
Recent Patches
The recent additions/changes to potions has been both a good and bad thing in my opinion. The health potions before the recent patch were a really good money maker and continue to be so even with the decrease in value. Unfortunately, this value is entirely attached to the Alesi quests and has nothing to do with their utility, and the crafting/stamina potions are virtually useless. If the devs intend for potions to stick around they need to do some serious balancing with food buffs, or make some system changes to the buffs (allowing buffs to stack or have different buffs between potions and food).
The addition of the catalysts, especially as a supply option, is a literal joke. No one in their right mind would use catalysts for supplies when the drop rates for fish oil are so bad and lower tier seeds are required for higher tier plants. The recent issues with higher tier resource respawn makes this even worse. Related sidenote: that catalysts are required in potions means making anything above T2, maybe T3, is a waste of time and resources, especially since quest rewards scale linearly and the input costs will scale exponentially.
