I think EOP was the clan that lost the most times while outopting the other clan and out-addying them. Takes a special kind of cauliflower to lose with both those advantages. On top of that they never amounted to anything, they've lost like every damn full out war ever.
2nd place goes to FI, they had everything in 2008 but that was the lowpoint of scape with PCL and nothing else. what they had back then they squandered later and disappeared for like 3 years. They had numbers, they had levels, they had defence and still what theyre most remembered for is losing to CP in a full-out and losing to FOE while up 16 or something. they seemed convinced that defence was the solution to everything and pretty much became a main clan in 2012. and even then they would still lose even opted every now and then. I think their 30 minute trip on the last day of runescape represented everything they were about and everything that they lacked.
honourable mention to the F2p version of Foe, idk how they remained so f*****g bad at a playstyle that is so easy to learn for so damn long. it must have taken a really cauliflower leadership to achieve the failures they did in that server.
