Chronicles achievements Easy to Hard to the Hardest

For players that have played D2R for an extended amount of time, the difficulty levels of completing the Chronicle bonuses probably look like this:

Easy: Making all the Runewords. This is particularly true since non-ladder and ladder share the same Chronicles. You can just use your old runes from NL to crank out all the RWs.

Hard: Completing all the Sets. This requires some farming effort. Some set pieces can be rare to find. Sometimes when I need a break, I just join a Shard TZ game and idle there. This way I may pick up random credit for some missing set pieces. You never know.

Hardest: Getting all the Uniques. This one could take a lonnnnnng time unless you are super lucky. Many people have found every single high runes, but they may have never seen a

Tyrael's Might drop, ever. Even if joining mf party is your main playing style, you are still at the mercy of the RNG lord.

...and then there's us who play exclusively solo self-found because we hate ourselves. Yes, I'm going for full log. No, I will not enjoy it.

I wish we had a proper SSF mode for this, like in Diablo 3. Leeching in public games is neither fun nor good etiquette.
The devs also missed the opportunity of adding proper achievements, which console player have since the launch.
