All i wished the rework would have been was that jutsu was still ogcd as it was, but wasn't broken by weaponskills, so you could weave jutsu with combo and still retain the same APM with just some less executional pressure.
TCJ is very awesome though. Think the normal jutsus could have also used a bit of the TCJ function, by making the 3rd sign button itself execute the spell.

It's very dividing either ways, i noticed ppl picking up nin who didn't previously care for it much, but my fc also had a long time nin main with frequent top 10 nin logs quit the game due to it.

Minor gripe, but i only used to have the jutsu button on the bar to follow the CD of the jutsus. Now it doesn't show the cooldown, just the sign buttons do.
