Yeti: Knockdown comes to mind. I can find more for you later, but knowledge specialization is another one.
Those are talents that require triumphs, so you are "required" to have skill investments in those to make the most (or any really) use from them, and their effects are pretty lame compared to improved reflect.
There is a general current (not you specifically Yeti) of Jedi power creep, and how we think these things should be reflected in the game. But for game balance first and foremost I think improved reflect is well designed (Aside from the fact you can get it without actual getting reflect, which is problematic at best). With the exception of adding a destiny point option somewhere to give more control to the players.
In the case of Knockdown and Knowledge Specialiation, both of those are built around skills that the character (9.5 times out of 10) is going to be improving those skills anyway, even without those talents.
