So I've "completed" 4 characters now this season:
Spiritborn: I did the normal quill volley build...didn't care to "optimize" it to hit for trillions when hitting for billions was already stupid with it. The class feels amazing and is so well put together... but I can't bring myself to play it because it's just so clearly broken and makes content trivial.
Sorc: I tried fireball and immediately just hated the way it played. I really invested time into building a chain lighting sorc and it's easily my next favorite build this season. It moves incredibly fast, it puts out solid damage, it nukes rooms... just feels really good. The problem is the damage ceiling for that build is very low. Wearing incredible gear in every slot except the amulet, I'm getting to about 150M damage....granted....that damage is coming out fast, all over, and with a ton of other procs...but it really prevents the build from going psycho mode. I've decided to give it a rest on the CL sorc and stop trying to keep pumping it because while it can clear all content and kill all bosses... when you're doing hordes with friends or running citadel it's still just not killing fast enough to keep up. It really feels like you need to be able to do on-demand 1B+ in order to feel like you're contributing to pretty much any group activity. Big shame, the build feels so good.
Barb: I made the mighty throw build and I just can't stand the way it plays. Having to bash enemies before you mighty throw makes the setup awful in group activities, and really awkward even when solo. I've always hated the way chains feels to group enemies. If there's a version of the build that ever appears that you can just spam throw hammers without needing to setup with some kind other attack first, I think it'd be one of my favorite builds. As it stands now, it seems like pit pushing is the only thing it's really good at, and that's mainly because you're just whacking at a massive pack of enemies for 30 seconds so the setup doesn't feel so awful.
Necro: I initially went with pure blood wave where you chase the waves and collect the orbs. It got it hitting really hard, but again the method of executing the build is way too awkward. I switched to the Spirit Wave version where you auto-collect the blood orbs with blood lance and shoot out a ton of bone spirits...which improves the quality of life dramatically...but the problem with THAT build is that the spirits are very random, and you can't group enemies fast enough to really make the build shine. Feels again like another build variant that obvious works well in pit pushing, but for general content it's too awkward to feel like you're really contributing in a meaningful way because in hordes your spirits are just going everywhere, and yeah they nuke whatever they hit....but there's been times where I'm just spamming it trying to kill something and the spirits just don't want to cooperate. It's just not where it needs to be.
...
So now I'm trying a landslide druid that uses shred to get around. I absolutely loved my landslide druid last season, but I know this season it's substantially worse. It still seems like it should more or less fit the criteria I'm after, even after the nerf. Seems like it can dish out high damage quickly, and where you want it to go. And with shred on the bar you should be able to get around the battlefield very quickly.
There's off-meta spiritborn that seem interesting like the Rake/Payback one that scales off thorns and doesn't use Kepeleke or that Sezsldkazoekaa (whatever it's called) like literally every other build does. My friend made one and he loves how it plays.
...
Just trying to find another build that feels good in all content, solo or in groups...and not just pit pushing. The hunt still continues. I'm hoping landslide druid is the answer.
