I would try it now if you haven't already. Try on a barb, then try on a magician.
See how you like playing both & then ask yourself, are you okay with farming 15 monsters dying 6 times, farming 15 monsters dying 6 times?
What would be your goals? Farm maps; farm eps; find great items; sell whites; sell mutes; use your finds for skilling? Just casually farm when you have 20 minutes to spare?
Are you okay with never gaining proficiency?
Are you okay with never MQ'ing?
Are you planning to drink potions for your death runner?
Are you going to wear stat/ML armor, ee/ML armor or just a pure ML armor?
Unlocking classes will increase the % of experience lost so instead of dying 6 times you could reduce that number to 5
(adds up tho)
BWConformity is the king of this info, and this type of farming. I did it myself for maybe 100hrs hours after months of planning, I was really excited to get it started and it was the most tedious and boring way to play this game
in my experience Try now & ask yourself if you could do it for 100hrs/200hrs/300hrs/etc, or would you enjoy playing the game a different way?
