The best of each guild?

Ranger - Lusts for Blood
Merchant - Asil of Kurac
Assassin - Ghost of Tuluk who shook up Nak pretty hard
Warrior - Excluding HGs probably Meso, Dargan, or Arjun

Edit: holy shit, my bad for only reading the title before posting.

Here's a thought. In a RPI, the difference between classes should be perspective based as much as possible versus hard limitations. There are many says to do this, but I'll limit my examples to easily codes implementations. You want players to see as their class, to feel as they are playing in their role, but not suffer from hard lines. A ranger could see further in each direction. Ingredients for crafting could have two flags randomly set, suitable and not, and only someone skilled like a merchant (or certain subclasses) could see. A warrior could craft a weapon for herself, but it would take determination. She would have to make many attempts trying different shafts, etc., where a merchant could have assessed each part prior to. Assassins could have an affinity bonus from marking and stalking their prey. The timer continues to increase as the assassin spends time examining the prey for weaknesses. This isn't to say that the assassin wouldn't have means of killing certain targets instantly (poison, backstab), but it's a way to allow one to kill more impregnable targets with some amount of time and risk. An assassin is hard to balance. We want them to be able to quickly kill a given target; we do not want them running around instakilling everyone. Given this perspective based approach, the assassin would have to masquerade in the presence of the target for some time before striking. It is easiest then, as in real life, to strike at the back of a friend. A warrior could set her own gambling ratios in combat (def/off). This could be called mentality, combat disciplines, whatever. When fighting three people, your only chance is to hope to kill one very quickly to even the odds - you rely on acting batshit crazy and being bold. Rangers could mark prey to some extent as assassins do, towards people or a legendary beast. The effectiveness of marking a prey, meaning the increments the timer collects in and/or the bonus itself, could be affected by wisdom. Merchants could use any weapon, but wouldn't be able to mark prey or control their ratios.

This is the approach I'd take if I made a MUD anyways.

Agron was around since before extended subguilds the way I heard it.

I love getting this kind of after-the-fact perspective. Makes the story all the richer, getting a behind-the-scene glimpse of the character's life-cycle.

Sorcerer - Hasan, Shattered
Drovian - Bryn. He's the dude that stole a steel helmet from Kurac, sold it to Shiran, who sold it to Kurac, then stole it back from Kurac, then sold it back to Kurac). God-tier Drovian troll.
Elkrosian - Bones. Badass who ran around and did all the things.
Krathi - Horoz. If the aim of Krathis is to murder and partake in the old ultraviolence, this guy won.
