I'm going to base off this list on how their calling compared to the time.
Ex. Fi James - 2008
1. The many callers of Epidemic - 2009
I personally believe that they revolutionized pure calling. They were the most notorious in calling strategic pushes, having multiple styles of warring, and using the full capabilities of numbers and mithril to defeat higher levelled opponents. This was most evident when they went up against MM for 3 or so weeks. Although they weren't consistently winning, they were fending off opponents who had an average of 10 combat levels above them. This is something along the likes of TLP fighting a clan with a lower combat average, such as Hostility, and trading wins.
2. 13th/Toxic of MM - The two full outs vs FOE.
I've personally never had the chance to call in a 100 vs 100, so I can't base how it would be called. However, to be able to beat a clan such as FOE two times in a row, not to mention pretty one-sidely in the first one, is something to be noticed. MM went into those fights with the statistical disadvantage, as FOE had significantly higher levels. During this span, MM also was fighting it out with EOP for #1 in F2P. EOP had statistical and the armour advantage, yet they were able to trade off #1 on and off. A feat to be recognized.
3. Drunkin R2H - The whole of CP's existence.
Although CP have had their slumps, for the majority of their span they have been relevant in F2P. For a person to be calling throughout the many changes of warring in F2P is pretty impressive. The ability to change his calling style, to adapt into the new branches of calling, to completely dismantle the old fashion of warring and take upon the new style without falling back too much is very impressive.

4. Walli/Kyle - FOE - 2010-2011
There was a stretch where FOE was dominating in F2P. Without the euphemism, they were totally dismantling their opponents. They were fighting the likes of MM, EOP, Fi and CP on the same inventory, with one defence armour, and coming out on top. They were pulling significantly more than their opponents, and were winning matched preps left and right. Although some of these accomplishments could be attributed to their numbers and levels, it takes callers that know what they're doing to show the dominance that they showed.
5. I think Zach calls for TLP in F2P, or Dissy teehee - 2011
When you think TLP, you normally think of P2P. However, in 2011 they showed that they could beat any clans matched. Their abilities in preps could be best noted when they beat FOE pretty one sidely with a significantly lower combat average. They were beating clans in the wilderness and in preps, with lower levels and P2P based members. Although their accomplishments were done mostly in clan wars, they did reign in the wilderness for the odd week here and there.
