Wish you could actually dual wield a sword on the mainhand and a pistol on the offhand. Would be kind of weird but it seems cool. You attack with only the pistol whenever the target is out of melee range, and actually dual wield when the target is melee range.

Stat OR Level requirements in gear. Wish you could equip gear if you either reach the stat requirement OR the level requirement. Makes pumping stats have a little more sense.

Cosmetic pets that could act as auto-pickup or an extra inventory bag. ;D
Torchlight isn’t the best game to tape ideas from. 
Just because Torchlight did it doesn’t automatically mean it is a bad idea. I myself wouldn’t mind Pirate-style fighting.
Haven’t actually played Torchlight but now that you mention it I might give it a try.
At first glance it doesn’t, but some ideas are inherently conflicting or very hard to implement properly.
I personally won’t mind pirate-style fighting too, and pets carrying your items won’t really affect the game much (I don’t think it suits GD’s atmosphere though), but Stat OR Level requiremenets is just very difficult to balance, so it’s not surprising that it’s poorly implemented in Torchlight. To begin with, this feature means that drops generally would need to be a few level ahead of you (IIRC in Torchlight you get items with level req. in range of -2 to +8 of monster’s level), because otherwise this feature just doesn’t come into play much. This also means that current requirements need to rise, because e.g. a Fang of Chthon - level 75 legendary item only got 341 CUN and 426 SPR - I could easily have such stats on vitality conjurer by level 35-40 investing less than a dozen of points into CUN/SPR. But since currently most builds want to pump PHY, not CUN/SPR, you’ll end up with situation when some builds just straight out win from this, because they pump PHY anyway, e.g. 2h builds), while others have to suck it up and just wait for level requirement, because currently investing too little into PHY means a weak build. If anything, this would lead to casters going all-PHY, because why aim for 700 SPR requirement for offhand if you’ll wear it eventually anyway. Pretty much this is what happened in TL2 - technically I can adjust stats to wear some pieces more early, but VIT stat is so bad any non-shield build wants nothing to do with it, also a rare build would want to pump DEX to more than 100+ when it’s STR or FOCUS that are key damage stats, but some items require an absurd amount of DEX. So most of the time you just wait for level requirements anyway, annoyed at the fact you almost never get to wear a good item you looted/bought asap. Why bother with such a system then?
