How won't this help much? The quest is fixed, and you have absolutely no hindsight on what can be worked on in this game and what cannot be worked on in this game. It's actually incredible how you've spent this long on these forums and still remain entirely negative and ignorant to almost anyone who tries to help you or agree with you, when it's all you ever ask for.
Braas, Marthog, Haenir, and myself are the only who have fully completed the quest to my knowledge. Ekyu and Relvos were among the few who did the quest a while ago but were stuck at the broken part with the gizmo and the activated named mob.
Fuwok did help me out with a lot of this, and should be completely working. I did think it was a bit over-tuned when I was completing it. Sure a lot of it is soloable, but some of the mobs in there truck, especially the named.
Having a tradeskill require a T13 warrior and cleric duo to barely scrape by on the final fights is pretty OP, and similar to Marthog - I don't think Scrap Heap should be obsolete and recommend following his thoughts as far as keeping the current quest line in tact.
At first I found myself pretty frustrated doing the quest from scratch with limited resources for help on it, but I had to admit after completing it that complex quests that actually make you think are pretty fun looking back on them.
For those interested with the current quest, I've started an introductory walkthrough on the wiki a long time ago. I've purposely left parts out because it'd simply ruin the complexity of the quest, so please try to maintain this if anyone's looking to finish it.
And for people who are stuck on parts that aren't included or need help killing something, PM me on Discord and I'd be happy to help if I have time.
