I finished my 2nd play through of DR, this time solo/hard. It's been years since I've beaten a game twice back-to-back.
Used a spear dodger 6(9)/10/9/9/4/2. Trident was by far the most useful weapon, followed by the hasta.
I kept spear and dodge at R9 until after the emperor, and alchemy at 4 which let me hit 10 crafting just after the enforcer fight. I was worried I wouldn't gain SP fast enough to get much use out of 10 crafting, but I did. It wasn't very hard this time around, easier than playing with a party of 4. Sometimes the strategies are counter-intuitive to me, like charging the crossbowmen in the molerat fight where you have 4 xbows on your flanks, and a heavy armored hammer guy in the center. The fights were you couldn't pull back were definitely the hardest, and I don't think I could have beaten the three worm encounter guarding the crafting chest the first go-around. I had to wait and take it from the other side.
I'll probably play DR again, but only after the final patch. Same for AoD.
edit: for anyone else under the same misconception as me, you can use the glowing jars to raise STR/DEX/CON any number of times up to 10, you aren't limited to just +1 per ability. I don't know why I thought that, but my killing power went through the roof when I went from 6 to 9 STR.
