odb one of the best players to never play invite imo

edit: the grape juice video and penny video posted by carter are great as well

https://youtu.be/BNyRZ9grL4Y milky video (just random one theyre all great)

https://youtu.be/RUMVM1OZK7U random rivka vid (they all crazy)

+1 on grix airshot vid

Because of the ETF2L data loss I'm not sure if these people ever played prem but the people I always thought were always had good vids were were rivka (mentioned here already), Aubriac (https://www.youtube.com/watch?v=GXjuL7OMqvY) and Joe/Garbage (but I dont think he wants his fragvids to be for public consumption).

I was going to count relior but I forgot he actually played a season of prem in s24 (https://www.youtube.com/watch?v=MNIyXJR7GKw). Surprisingly hard to find people with good frag vids who never went on to play at a top level.

tickle is goated

as buud already mentioned, basically all of the milky fragvids are pretty sick:

larval was such a monster but never had the time/motivation to full commit + the one prem official he merced was for europes top seed at the time and he fisted on viaduct as roamer imagine

morni makes crazy vids but he doesnt post them so nobody watches them
EDIT:
evans never quite made it to prem unless you count playing for nunya at i61 as being a prem player and his videos are insane

https://www.youtube.com/watch?v=iIL9V8pdqgw - konfy by dob

boomer answer but konfy was part of the non-brit dotpixels package (thalash, ipz, smzi, konfy) and was the only one out of the 4 to not go on to play prem, it doesn't look like much nowadays but this was almost 10 years ago, these were a+ rockets at the time

This one is kinda like what mould said. I always liked Biester video's back in the day. Perhaps not impressive for today's standard but when I saw his vids the first time I thought they were nuts. He also used a bunch of funny huds.

Sadly he removed almost all his video's :(

Same goes for Berrtech actually.

Forgot about this but I also really enjoyed mundi's fragclips.
Here's a compilation of airshots https://www.youtube.com/watch?v=-My19DMERuk

yo wtf this video is incredible

guy probably hasnt played tf2 in 10 years but charged light had some beast frag videos: https://www.youtube.com/watch?v=llEyOoYothc

oh also I should contribute: thorn was a beast and I don't think he ever played in invite for a full season? correct me if I'm wrong..

https://www.youtube.com/watch?v=qiN9vGdALdw

if this dude is legit he has the best tracking i've ever seen. same tier as quad

Ya man, I never had any reason to doubt him over the years that I knew him/played with him. From what I remember he was like, one of the OG dm lords that just ground out ungodly hours in dm (in addition to obviously being incredibly skilled regardless)

If he's quad, then I'm five. See you in 2 years.

It's Seeeeeaaaan
