I was in eternal div 1 in past season, but you need to farm in order to build. I was much more focused on farming build than pvp build first. Now that i have build that i can farm with i could focus on pvp.
Here are the scrrenshots with Rouge beating anyone with items jaspered fom warrior. I changed only the offhand skill to match my warrior skill im using.
I can get 3:0 wins with characters I lost if needed too. It's harder to win than with warrior but I have useless offhand primary skill becouse I could.
About copying build. Yes i did that when I was starting my adventure in pvp, when i didn't know the flat elemental damage is better than 100% legendary elemental damage in pvp. I was learning. When I learned more i started to change things I was lacking. I don't want to copy to be the same as my opponents. I want to be better, not the same Also didn't saw anyone using Fabled Blade in PvP? Maybe they didn't had as good luck as i had with it. Also I will always think Alchemy is best mythic resource for me, but until Glasscannon with Alchemy is not fixed i can't use it But that doesn't mean Rouge is good. I can say, warrior is good, but i don't play Rogue so i can't say if it's good or bad. would need to play it more.
