well MQ is not a great example, because even builds that own her on youtube tend to spike up and down in HP like they’re having a seizure. that’s a far cry from one-shotting rift bosses in Diablo 3. Also look at the loot comparison- MQ will drop NOTHING whatsoever in 19 of 20 runs (maybe a legendary or two, mostly blues, and small chance at ONE copy of her own legendary).
in a game like Diablo bosses drop tons of high end items your character can most likely use. This means in GD it’s not one boss kill, or one run at a high end roguelike dungeon that gets you loot you might be looking for- it’s DOZENS of such runs, and they each take about 10 times longer than a greater rift in Diablo.
so while there might be a few very minorly OP builds in GD, the grind itself is VASTLY OP compared to any other ARPG as well, and these must be balanced together. i enjoy fighting the same areas on different 85s to compare their relative power levels, and seeing where i need to fine tune and optimize. loot happens by accident because it is SO difficult to find high end items you need that if you plan on farming anything specific you will rage quit (in 30 some Anasteria kills ZERO legendary helmets for example).
So i’d have to say GD is the most balanced ARPG i have ever played, and it’s not even close. The genius of this game is player generated content- you can take the WACKIEST idea for a build and if you really get your GD-scholar on you can turn it into something incredibly powerful. as it stands right now i don’t think there’s a single build in the game that is so OP that it needs further nerfs- and there’s less incentive to play FOTM in this game to begin with since the builds can vary so wildly. i think we’re in a pretty good spot
