Most powerful Jedi of the pre-prequel era.

By which I mean before Yoda's birth.

Adelade (amped by Gethul?)
1. Revan
2. Meetra Surik
3. Jaric Kaedan
4. Satele Shan / Lord Hoth
5. Satele Shan / Lord Hoth
6. Alek
7. Jedi Ulic Qel-Droma
8. Vodo-Siosk Baas / Thon
9. Vodo-Siosk Baas / Thon
10. Celeste Morne / Zayne Carrick / Bastila Shan

Looks more like a Pre SWTOR list.

Asides from a couple.

The lack of HoT and Barsen'thor is disturbing. Also Jedi Kun. Lucien Draay. Aryn Leneer and Ven Zallow.

Fae Coven, also. Odan Urr and Ood Bnar could be honourable mentions.

new list

1. The Hero of Tython
2. Adelade
3. Foundry Revan / novel Revan (whichever you think is stronger)
4. The Barsen'thor
5. Meetra Surik
6. Satele Shan / Lord Hoth
7. Satele Shan / Lord Hoth
8. Jedi Ulic Qel-Droma
9. Jedi Kun
10. up for debate; probably Ood Bnar or Vodo-Siosk Baas

I changed my mind, since, even though Alek is implied to be greater than Mandalorian Wars Meetra Surik, he still got his ass kicked by Mandalore the Ultimate.

What has Hoth done for him to be placed on this list?

You don't think someone like Arca Jeth or even Worror Dowmat is better placed than Hoth?

1. Revan

The rest.

Pre-prequel era would be the 1000 years between the Ruusan Campaigns and The Phantom Menace 'era'.

I meant prior to Yoda's birth, as specified earlier.

Nomi Sunrider?

Whoops, mis-read the OP there, damn work.

I wouldn't count Adelade as one tbh. It would be no different than using Mortis anakin, etc.

Feats for Adelade?

Some FP, that the End of KOTET Outlander and co take on.

Does she do anything impressive (ex. Darth Soverus) besides dying?

No, was pretty pathetic tbh.

It's just a random. Why she's so high is beyond me.

If she had a decent context/Story behind her, relevant to the main plot then maybe.

But other than that, i'm guessing they have her so high because of being amped by gethul.

She seems really cucky. Wouldn't put her high tbh
