I agree with the bolded part
Rake.
What sort of Barbarian did you have? Mine had Savage Attacks, One-Handed Mastery, Weapon Focus Sword, not a tank, but dealt tons of raw damage. Wild Rush is fun too, and extremely helpful. Both defensive and offensive (breaks disengagement attacks too IIRC). Repositioning etc. Much like the Rogue's "Escape", but to get into combat instead of out of it. This was on Easy, and this was my first successful Barbarian, all the other got squished (they seem to be pretty fragile and/or easy to hit).
Though, I wonder if the Rogue can become a bit more bardic, and perhaps have some lighter version only ally buff Chanter songs path in skills.
I also made an Aumauan Wizard Duo, BB Wizard, BB Fighter, BB Rogue, BB Priest, on Path of the Damned/Trial of Iron/Expert. Nyfre's group didn't stand a chance. Wizards are extremely fun in groups, and extremely powerful, but perhaps there was some expectancy in the air that there'd be 5'000 magical and fantastical spells that we were all thinking about collectively in different, equal, and opposing views, and trillions of schools of magic would exist. It'd sure be amazing, but reality exists too.
Wizards are most fun in groups I find, where one Wizard is one type of Wizard, and the other is another type of Wizard, and together nuke stuff into obliteration. I'm sure more spells will come out of expansions and mods as well.
Druids would be more interesting if they were split up in Generalist/Nature Druid, and Shapeshifting Druid, I think. Ciphers, Monks or Rangers I haven't gotten into much yet, Fighter is pretty standard with some improvements, Rogues are pretty familiar as well (apart from that everyone goes into sneak mode when sneaking, instead of individually), Priests are also pretty familiar. And Chanters are really fun.
