There are one handed ranged weapons - daggers.
Not really. The fact that you use a weapon doesn’t mean you have to hit only with it. Casters exist.
Nope, daggers are one handed and you can dual wield them.
No. There are weapons that increase other damage types. You can deal heavy physical, pierce, bleeding or poison damage. Rune mastery converts weapon damage to elemental
They can be elemental too. Basically bows were designed for pierce in general, they were not supposed to support other damage, but there still are theme weapons that give you huge amounts of elemental damage, poison and bleed, effectively making bows do other damage types. You can support any damage on any build, but there’s an issue with RR.
Casters are strong if you know what you’re doing. Summoners are way better because you can focus on yourself AND your pets. They have most likely the highest damage in the game, but, again, you have to know what you’re doing.
It’s not possible in current game version.
There’s a farm-fest dungeon. Most (or even all) oldschool ARPGs do not have end game. They were basically design to make a character, push it to the end of legendary and then farm for another character. Same as GD was before FG.
Which are re-designed skills from TQ. Not all but still. The variety is, for sure, not higher than TQ’s, maybe if you take in account Devotions, which is a stupid (useless) mechanic as for me. Building a character usually takes hours in GD.
Which are still outclassed by any melee build. Two handers can hit hard, yes, but in comparison to, e.g. dual wielding they deal less damage. You can crit for 800k, yes, I agree, but a dual wielding character will do the same or even higher damage. If I remember correctly, dual wielers usually do 1 million damage DPS if debuffs and other important stuff is applied. In TQ you do not have anything like “x is better than y because it deals more DPS”. It’s only the case for dual wielding, which is restricted to two masteries - Warfare and Rune. You can not get it by any other means.
