So now that I am playing the Necro for about 2 weeks and have tested several builds either for GR or Speedfarming I wanted to share my accomplishments and share my thoughts.
1. I Play with 1313 paragon atm.
2. With Trag'Ouls build I cleared a GR88 with crap gear no Augments and no ancient weapon. (Topping leaderboard-build)
3 With Rathma I cleared a GR84 with crap gear no Augments and no ancient weapon. (Bigdaddyden's build with insane life-regen.)
4 With Inaruis GR Build I only did GR80 so far (post nerf) / The Speedfarm-Version with corpse Explosion is also very strong and funny (Zombeaver's build)
5 With Pestilence I tried the Exploding-Spear-Speed-Build (LordFluffy's)
To 2: Sure highest potential as seen in leaderboards but that gameplay .... oh man ... dodging around and waiting for a big cd to come off .... sucks for me.
To 3: Very funny to me as I love pet builds in General. Can some1 say something about a viable Thorns-Pet-Build pls ?
To 4: My favorite ! I love both builds and the playstyle of Inaruis.
To 5: FOr GR60 and T13 great and funny but as said many times the worst set. Expl Spear is super funny gameply but not viavle for GR or has ony1 seen a Pestilence build pushing 80+ or 90+ ?
For me it's clear, Necro in season and for Rathma's being the free set this is great pushing the first GRs and when I have Inaruis and the other stuff I am speedfarming and pushing with Inarius. Most fun to me and having both in 1 set saves me much work and crafting mats.
The only thing I can add is that Rathma probably won't be the go to build for any group comp to push high GR's. Trag Blood Lance will be the go to for group GR because it is currently the best best boss/elite killer other than Wiz Archons.
