Is TP interesting as a mechanic?

[Solaiel]

Well right now i am not sure how to make it more interesting. But there is one thing i would like to address thought on, because it is going to be an issue if things go further the way they are, without tp to change.
I am not sure if someone mentioned this already, so excuse me if i say something you know already, but it bothers me a little.
Right now on my pld equip of course i try to stay away from parry as much as possible because its useless. But i find myself with a lot of skill speed stuff at the moment, because choices right now are not the best for plds.
The result is my tp are quite fast quite empty and in fights like a9 not even half of the fight is over and i have tp problems. That kept me thinking.
Because at the moment we have like 1000 tp. they regenerate with a set amount per tick. some classes can very well raise tp a little, but if the current itemization continues, where will it end?
I dont know if there is cap on skill speed, but equip is always getting bigger values in stats. That results in always having to take less gear to get the same values in speed.
If nothing is done at some point we will end up either wasting stat points on speed that are useless, because we are already above the cap or we will be literally fast as a greased lightning without being a monk.
So i think before a complete overhaul should be done, we should also think of preventing such situations, because this wont as much time as a complete revamp .
Also keep in mind that just removing tp as a whole will result in physical dds dealing way too much damage. Maybe a cap on skill speed would then be needed or something of the sort, but i think now is the time to at least work in the direction to prevent this problem, because the process is already going on, if you catch my drift.

Reducing all TP natural and bonus ticks by 20% but having them tick per player (base) GCD is an idea I and a couple others have passed around a few times. The idea would then be that there's virtually no additional TP drain for taking skill speed. 2.5 GCD classes would keep the same TP regeneration rate; the rest would be slightly buffed.
