The fact EOP is only relevant when 07 servers came back should tell you how much they didn't matter back in the day.
Oh and i'm going overboard because fuck a top 5.
1. MM (Forever based on if u think #1 f2p or #1 p2p matters more)
2. Foe
----
3. Fatality (Their good Era had them at #1 ages ago)
4. TLP (#2 P2p without a question always beat MM lost to Foe in anything past 70 v 70. Eventually became relevant at f2p)
5. Eop (Disgustingly trash at p2p server but did keep up in f2p)
6.CP (Good f2p, couldn't even beat Bloody Vikingz in p2p back in the day if they wanted to)
7. Destructive Pures (Solid Clan, better than Tlp at f2p and better than CP at p2p but worse than Tlp in p2p and Cp in f2p)
8. Epidemic (Only non legacy clan to arguably take #1 F2p during the hardest ERA to become #1, unfortunately booty at p2p)
---- The Who Cares Gap, these clans randomly did something and then nothing ---
9. IR ? I guess? A Legacy clan that never shined was just always there.
10. At this point i'd just toss in CD because that seems to be the meme.
Remember your post said All Time but also remember 2007 server runescape is the easiest Era to be good at. You want a "tough" era for competition The years 2008-2010 or mainly 2009. If your clan was good in 2009 then be proud otherwise I don't care about your history.
