Dear community mannager , we ranked GR 150 NO.1 now, but i have some experience want to talk to you , may be some right or wrong ,please kindly read about it
1 NEC can kill the monster but the Elite monsters only 20% heath dropped , that why we can’t make the Volley Damage（AOE）
2 WD have not enough defense for GR 150
3 WIZARD about the hydra has been Too much weakened please add a Bracer
with increase 500% that can help us easier to have a good experience for quick GR
Watch out for people who will complain about necro making season 20 too easy for them and demand nurfing 
Even though necros will be powerful in groups in S20, I have little sense about where they will end up solo.
not a good experience ~~~~ so hard
