The necro still overshines the other RG killers. And despite their post, i think this is just because of $$.
We had a nice competition between DH and Wizard last season.
This season its necro all way, i am fine with that. But when the innarius bugs (skeletton hit mechanig etc.) do not exist anymore
the necro will even be stronger. The main problem is this infinite, stricken-like damage increasing necro item that should not exist imo.
And it already cleared 132 in its current version...
If they would scale it down a little bit to have a competition for the RG killer again, that would be nice, but won't happen

The only problem i have is that pushing the GR gives u a disadvantage compared to keep farming till the last weekof the season and then pushing.
If they could invent something different from xp that you gain for solo pushing your GR (e.g. some mats that you only get solo or whatelse)
Then pushing midseason would not feel as stupid as it does now, especially for the non casuals.
I think its best to have a balance between solo and groupplay and that could help.
