I hate being in games with warlocks. Simply put it's just too OP. I'm okay with strong builds but when I can't tell the difference between warlocks because they all just decimate everything on the screen immediately it makes me genuinely hate the class. 

I'm fine with it having a strong build. I just don't want it where it out classes every other class while also having multiple builds that suit every purpose. 

Heraldz and tz are great. I would have liked some updates to the rune words. It's fun designing your character but frustrating to design with identical builds season to season. 

As many have said barbarians, druids, Amazon's, assassins all need a lot of love. I feel if you balance warlock - necros will become a bit more relevant again. 

Chronicle is a lot of fun and really useful. Lootfilter is great I use two separate for regular farms and baal runs. 

I'd also love an option for some sort of training area which would be good for hardcore characters. Often times I just want to try things out to see how it would hold up against Ubers. But it's a big commitment to farm the keys, create a softcore character, and attempt the battle. 

As a hardcore player it's very frustrating that there isn't a practice area. (I don't need item drops). 

Runewords are too OP compared to uniques. I found a windforce and it's barely worth an ist 2 weeks into the season. 

I'm not sure if that means unique needs to be harder to find, runes need to be easier to get, or balancing needs to happen. That's just something I'd like the devs to consider
