Chronicon

• Every class has at least two Legendary Sets per tree/element. If there is a playstyle you like for a given element, odds are there is a Set that boosts it. So don't feel pigeonholed to play a specific way. Also, respecs are free so go nuts trying things out. Talk to the old man who gives you quests for a respec or to move points around.

• All the trees are viable, though I wouldn't say they're all equal in power level. If something seems interesting, go for it. You can almost certainly make it work just fine.

• It's okay to start on Heroic (though the first half to two-thirds of Act 1 will be slow going), but I wouldn't start a fresh character above that.

• Hardcore is totally viable solo, and I would even say blind. There's no jumping across instant death pits or "press X to not die" moments in the story.

• If you truly have no idea what class you want to play, Templar is the easiest of the bunch and has a bunch of diverse playstyles based on the given sets and elements.
