I am pretty sure he can only use the abilities of his legion, so you can disregard that part about being able to use your abilities on a meta-level. And their brokenness is a bit evened out by the fact that anyone with a taikyoku rank equal, close or superior to Reinhard's could fight with him regardless of how silly the concept is.

And he only has all of those abilities due to his Legion. Something Fuji Ren can do as well. Honestly, I am not sure if the Legion ability is part of a Hadou God's repertoire, but those two have definitely shown it. The difference being that Ren has to establish a connection of sorts to his legionnaires before he can use their abilities at his level.

There is also the fact that he needed a lot of Holy Relics and sacrifices in order to become a Hadou God. Or well, to reach the state of Atziluth.
