So, I am a newbie in Median, have played before Sigma a little and at its realease.
This league I got to Hell Baal with SSF Ice Sorc with about 10 deathes. Then I decided to try another class, because I collected a lot of uniques (whitch can be crafted with Ench Oil + 2 arcan crystals ^_^ ).
So I twinked Amazon, because I like her. I tried her in previous leagues but she was so hard to play (survive) and now game is easier (Act 3 Normal Kurast mobs are now like 0 damage and many others too). But even twinked Amazon, I follow your guide, thanks, dies so often then SSF Ice Sorc. I think that I definitely have 200 deathes (First death was on Normal Baal though - I got Flamestriked with 75 fire res, but now I better understand that you need always move >+<).
I took normal Barb merc, because they were strong, but now I feel that he isn't nowadays.
Ecstatic Frenzy on or off makes not difference in surviving, I think because dodge and defence passives we don't max. So leveling was much harder then sorceress' one. Even Paragon at lvl 90 didn't help.
I ended with lvl 109, wyrmshot damage was 1200-1900, 6200 hp. Akara's Rob, Featherclaws, horrific belt (res, dex, str), Herald of Skartara (perfect skulls, ed, 2s mana steal), Siegfied, Hanabigami Quiver. And here is Stats picture.

So I don't know what I was doing wrong or maybe it is just Amazon's such character on Median (but she even doesn't feel like glass sword sorceress, she's just glass).
Thanks for guide once more. Stay safe!
