Terraria: Journey’s End includes a full re-visit to all elements of Terraria. Over time, some things may have felt left behind or made obsolete by newer content. No more! Old things made new and new elements added to flesh out the overall experience – think you know all there is to know about Terraria? Think again!
Outside of the usability improvements, this is probably the thing that has me the most cautiously excited. Ever since Terraria 1.3 introduced Yoyos, Flails just stopped making sense. Yoyos are more controllable, can be crafted from basic materials, do more damage, can have longer range, can be guided around obstacles more readily, and have a bunch of cool accessories to improve all of these. By contrast, Flails... exist? Oh sure, one or two flails give interesting status debuffs (the Dao of Pow still has a place due to its confusion debuff alone), but overall, they just don't matter anymore.
So I'd love to see them do something mechanically to allow them to compete with Yoyos.
Similarly, since 1.1, arrows have felt like an also-ran to bullet weapons. Pre-hardmode, there's a real difference between the two: guns tend to fire faster but with lower damage, while bows fire slower and are harder to aim, but cause more damage per shot. But post-hardmode, rather than improving their damage and keeping their unique aspects, bows just became slower-firing guns. And the sniper rifle is really a bow that fires bullets, thus taking away the one advantage using bows had: high damage.
Sure, there are a couple of late-game arrow-based weapons that are worthwhile, but most of the Ranger-time between beating the Wall of Flesh and getting the Tsunami (or maybe Chlorophyte Shotbow with special arrows) is generally spent with guns of one kind or another. And even then, the best bow, the Phantasm, feels less like a bow and more like a gun with a weird mechanic.
I would like to see them restore the difference between guns and bows in early-to-mid hardmode.
Oh, and if fishing could be made not to be horribly boring (or to at least not require constantly going back to base), that'd be good.
