Twisted engage has always been that. Heck, it used to actually have a longer range before the rework. As for no counterplay, the range is not nearly as good as other engages. That does constitute counterplay, because stopping the engage does not require to be unreasonably far away.
In his rework, Maokai got significantly more W damage and he got a sticky ult. Because the damage is not core to his identity, it's the first thing that's going to be targeted. Given that his base damages are still quite good, I'd wager they can still afford to tune more in that direction before hitting his core concepts.
