I started playing HC in 2020, & was on Bloodsail before the addon, when we had to record our entire run & have it reviewed.
FFW to this june when I killed my computer's motherboard during routine cleaning, only to finally replace it yesterday.
MIssed Launch & all the fun.
I find there to be a huge amount of corssover between HC & F2P WoW. True Solo-Delf Found Hardcore is a delightfully slow & methodical crawl while leveling, but every single thing you can do to make your toon more capable of survival is absolutely worth it.
150 fishing at lvl 10: Worth it.
grinding chests in Durotar for silver bars & green gear: worth it.
farming grey mobs for crafting mats & buff scrolls: Worth it..
The only TRUE meta is: SURVIVAL
I highly advise you to give HC a good solid try. By that I mean: don't quit after an afternoon of getting clapped by respawns in Fargodeep mine.
The HC mantra echoes loudly: WE GO AGANE
