Ironman used to be a thing back in D2. I dont really see that anymore but then Ive only ever played solo on D3. Just easier for me that way.
I only play Hardcore. For me there is no value in something given randomly that you can never lose. Value is created by rarity to replace, not rarity to achieve.
For those reasons: Hardcore gives my game; value.
Adding to it the Seasonality makes it even more valuable.
For the longest time I’d play close to ironman, starting from scratch at the hardest difficulty playable. This means for most characters T3 to T4 starting from lvl 1 no gear.
But to be honest thats been a been a bit of a grind.
With the right balance of armor and all-resistance (1:1 ratio) then T1 or even T2 starting from lvl 1 no gear is quite doable and “safe”.
Hardcore really teaches you to be skillful in a lot of ways.
Often times I find myself dodging arcane sentries or ice novas for many levels before finally being trapped by one and realizing it was quite survivable, but just because in Hardcore you never take damage you dont have to.
And a fight for your life such as hacking your way through a mob of elites that trapped you is infintely more rewarding.
The gear is just a tool. The challenge is the only reward.
I havent really noticed DC issues but perhaps its the solo play minimizing that.
