To be frank, Anger Point isn't that great of an ability at all in doubles. Let's take a look at who has them:
Camerupt: The camel will never step into the realm of VGCs hardly. It's piss poor in taking hits from Surf/Earthquake and is really slow. Even with TR support your still bad defensively.
Primape: Too frail to take a hit and there are better options to use like Hitmontop as a fighting type.
Krookodile: Again like Camerupt but weak to Storm Throw which is hardly seen because of the distribution and Ice moves are quite common in VGCs.
Taurus: though it is fast, it's not going to take hits quite well from Garchomp, Hitmontop, etc.
Overall it's a suicidal ability despite the high risk, high reward factor.
