Playing for so long on necro summoner and I see no improvement base build on necro must be summons and there is a problem we didn’t get any gems for summons. Full build on mages with golem will take 8 second to spawn mages is to long other classes are ready to fight full Skillz in sec 0 , I must wait 48 seconds to make full mages , why we can’t play fair in game like other classes, 4 years and we don’t get any improvement. Please help us to spawn mages more fast like 3 in same time 
.
Gems are not class base so not what you are looking for. What is more relatable is gear essences. There will be a new release of them when the next difficulty arrives so hopefully they add some that will work for summons.
Yah that true, don’t see so much efforts,I think better to improve summon time for mobile mages and abought gems they forget summons . Looks like they try with bone spirits but they have big cds , them esance who make them sommon don’t work full time and I got a lot of beneficial ,the summon have 4 sec CD , I think they “developers" don’t play this game :)) and don’t try builds before release :)). If they try to kill one raid ,new bosses will understand fast what necro summoner needs.
Summons is for farming open world, and maybe dungeons. There’re better builds for everything else.
That’s irrelevant. The summons are the class defining feature for the necro, they should viable for everything, preferably the best option.
Why? It was never the best build in d2, or d3. It was mainly a leveling build in both. Why should it be the best now?
