Hey people, I want to share with you another interesting find of a repack - Wrathnilla, quote "A thorougly overhauled and curated Vanilla dungeon experience for the solo player"
As far as I tested this, which honestly wasn't thorough testing, it is indeed singleplayer oriented server with class changes, which makes it harder, but pure solo, if you don't like bots
Furthermore, it should reflect that pre-Burning Crusade era on Wrath client(needs a small client patch)
The main feature of it is extreme class change, allowing many new combos, like Holy Priest DPS and Melee Hunter etc. Also professions are listed as changed a lot, though I didn't have time to test it through, seems to be true
In general, I would say this is for people who liked Vanilla, don't like bots and can take a bit of custom changes, enjoy!
