I wonder what 1.3.1 will bring. And why revamp Hell, it's already got quite a facelift.
Completely. Disagree. A few red devils and a background doesn't really do it justice. It's still easier in Hell than in the Jungle, both in hardmode and pre-hardmode, which is just counter-intuitive and ruins any incentive to explore the Jungle.
The place needs new mobs, new types of enemies, natural hazards, and most importantly: New loot + game mechanics. It needs this not only pre-hardmode, but especially post-WoF. I'd prefer if there was some kind of lava-inhabiting creature that is a near-guaranteed death sentence so players would have to watch their step, as well as occasional danger zones where you risk encountering even more dire things.
I want the place to be an actual Hell, damnit, not just some gimmicky cavern layer with a bat on fire. It's supposed to be evil and fearsome; not safer than the jungle.
The Dungeon has received the most major facelift I can think of, and it's a better one. But all they did with the Dungeon (at least before 1.3) with Hardmode was add a few new mobs. No, that's it. No new chests (But you can access a couple of ones that were specially locked, albeit you get the same items every time anyway), no new dungeon mechanics or types of hazards in the environment, the appearance of the dungeon is identical, there are no Events going on in there.
All you really got in the Dungeon was a chance to obtain new drops. Thankfully, the Diabolist was actually difficult a lot of the time, and the Necromancers' ability to hit you actually forced you to think. But that's it.
Keep in mind, I haven't actually gotten post-plantera in 1.3 yet, I'm taking my time immersing. But so far, all I recall new about Hell is the fact that Hel-Fires drop all the time, and the graphics are vastly better. It needs more "Hell".
No seriously. I want her to be a boss, I have an elaborate idea about her too, including Mirror Glasses that lets you turn her power back on her ;D
