Can we see the ones that won last year?

Should I buy "Hammer of Thor" kit? I already have Isida M1, Railgun M1 and Hornet M1. I am looking for a mid-range weapon, but I really can't decide. I mostly play on medium-sized maps. I am not sure if Hornet can handle it, but Viking M1 (included in Hammer of Thor) would be quite alot stronger. Even bigger question is what torrent. Help me! :)

Got a question! I got 500 crystals, but I have no idea, what I should buy with that.. I could buy Thunder m0, or Railgun m1. Which one should I buy?
