12/6/2 is still plenty nice. Not so much with same classes as the days of Cletus centered ESOS kensai.
Being centered is less attractive after heavy armor. Pajamas had a good run. Evasion didn't get shit on quite as hard but 2 monk/rogue is not the source of survival it was.
Kensai's T5 competence bonus got shit on by Swashbuckler's Level 3 core.
Ranger, AA slayer arrows are still what they are. T5 Tempest Dance of Death is fucking amazing, although maybe it always was and I just didn't know it. Probably just me late to the party.
One current 12/6/2 is Bard/Fighter/Rogue.

Rogue not so much IMO. Pally and Bard play really well with multiple break points on splashes. IDK what you'd gain splashing with Barb that would make it more attractive than pure. Rage still doesn't play well with others and the best enhancements scale with Barb level.
Shiradi casters can go Fvs/Wiz/xxx. Fuck I did that like 4 lives ago I can't remember if it was 12/6/2 or 12/5/3. 11/6/3? IDK. Basically enough to get max number of MM and CM through things that will bump your Wiz caster level. Secure's thread on the motherboard has one. IDK what else you would start deep splashes on a caster for.
