I certainly played both Diablos. I played the first one a long, long time ago. I chose the "stocky guy," and I was killed by skeletons. I was probably 5 or 6 years old then. Later, I even made it to the Butcher, playing as a warrior, shooting at him with a bow through the bars, but I got tired of it and stopped playing.
About a year ago, I played it again. Again, a warrior... it got boring. Then a monk. I ran around without armor or weapons. A monk is actually better without armor and weapons. I made it to the lair of the bloodthirsty insects, reached some kind of crypt, and got tired. A mage... I killed the huge skeleton of King Leoric and got tired.
In Diablo 2, I also played a long time ago, with different characters... mostly a necromancer. I remember when gear dropped after death, and I waved my fists at the bloody crow. Then, with difficulty, I reached Andariel, who kept killing me. In 1-2 hits. I was probably about 10 years old then.
Then I played Diablo 2 again, when I was about 15. I made it to Kurast at most and got bored.
And finally, this summer. A trapper. The one with the "very stupid traps to level up." She's overpowered. I really love melee assassins, with Tiger Strike, Claw Mastery, etc., but an assassin who has leveled up Lightning Sentry and Death Sentry (lightning trap and corpse explosion trap, respectively) clears mobs in a couple of seconds. A couple of LS, 1 DS, and that's it, a medium-sized hall is cleared. Contrary to the specialization, I didn't level up her mana. It was a bit difficult at the beginning, but blue potions solve everything.
I run Nightmare Baal at 5 players in about four minutes on average. About half of that is spent running through the halls. The rest is Baal and his entourage.
I've already opened Hell, but I want to farm in Nightmare for now. I don't remember the level, something around 60-70 with a Hoto. It's my first character that I fully leveled up from the beginning to the end with my own hands to a high level. I haven't played in about six months, but Diablo is still installed, and if necessary, I have an assassin in Harrogath with all the gear, so I can just jump in and farm the Shako.
The damage of the traps is 1-7000 xDDD.
That's for one hit, and there are about 20 of them, and that's just one trap. This is far from the limit; I've heard that you can get it up to 20k by fully leveling up the synergies and getting items and charms with +skills.
And I don't even mention DS; corpse explosion is what I love so much about the necromancer, and therefore this trap too.
In general, the assassin rules. I also leveled up a werewolf once. It was fun... I need to raise a Hammerdin sometime for complete happiness.
P.S. The barbarian has only 1200 HP at level 66, oO?! Did he level up mana or something...?
P.P.S. Fully leveling up Burst of Speed for the assassin is stupid; after a certain level, the increase is very small. And block too. It's better to invest more in Shadow Master - a great distraction, Claw Mastery - a must-have for a trap assassin, and Dragon Talon - the best final skill, it unleashes charges with two claws. So if you're not using it, your damage with Tiger Strike isn't 12k, but only 6. And the skill damage is also good. On the left mouse button, ;D.
You can throw extra points into Fade (resistances) - on Hell, Fade >>> Burst of Speed.
That's it.
P.P.P.S. There is no level 100 in Diablo. It's not good to lie about non-existent characters.
P.P.P.P.S. And you couldn't have gotten such high skill levels without bonuses from items, so don't brag.

The more I read and realize the facts presented in your post, the more I notice that "something doesn't add up."
You have about 1k damage with a claw? I don't believe it. With any possible leveling, without skills, the claws can't have that much damage.
And how, by the way, did you not manage to kill a sorceress with 12k damage?
I understand, energy shield, etc., but... "it doesn't add up."
