AE 2012 Tier List? + Viper Question

Does anybody know a reliable AE 2012 Tier list? Please post if yes and also what is Viper’s worst matchup in AE 2012? I can’t find the answer…

Thanks & Sorry if this is in the wrong section

There really isn’t a reliable tier list yet.

Viper’s worst match up is another Viper, or someone that knows how to block.

Yes, wrong section.

2012 hasn’t been out long enough for an accurate tier list, metagame is still formulating
