I don't think the required wins should be lowered I just think the thorn should get a Nerf ASAP....Every other match I played of Trials was a full team of thorns...Yeah will Extremely good teamwork you can counter them but still it's one thing to counter them once but every other match is just too much....and yes I do have a Thorn fully upgraded and yes I did use it in trials...it actually got me to 8-0 and then I lost to a full team of thorns...but anyway yeah just Nerf the thorn and everything will be so much easier
