Indeed. Amir got some nice material. I really like your prooves. They involve the years 2007 untill 2012.
to Night - the thread is named best Sheeptagger in history, so every year has an important role to the answer.
People who I would nominate/mention for sure are:
Exalius, Amir, Chaise, Shoop, Drew, Traxx, Cmk, Sidey.
It is really hard to rank the best of ever. Everyone is good in their aspect like..
Exa at teamwork, Shoop at wolfing. Whatever.
But I have to say.. Exalius has always been my favourite Sheeptagger. He always takes care to his allies. He helps, risks and gives all he got to let them survive. He actually plays smart and is no egoist ( e.g. golding ).
I STILL rank CandyManKiller #1 because he is overall the best. He is dominating Sheep Tag for over 3 years now and he is still the best. If you are with him you will survive longer. Even if his teamwork is not as good as Exalius' he is the guy I would ALWAYS take as first. You can always count on him.
