This is not a bug, intended feature. Frenzy is supposed to break through a saber block.
Despite the fact that it specifically doesn't state that in the ability description, fine, but why does frenzy make him immune to force abilities. I've force blasted him countless times and he ignores it while frenzy is engaged, even when being force pushed from behind and the aoe repulse.
When I'm hit by a force power while using Frenzy as Kylo Ren, it always connects. I get knocked all over the place when I'm doing Frenzy, particularly by Luke. I think there are a couple of things at play with Kylo's attack going through blocks. The primary thing I think is happening is that your stamina is empty, so you can't block anymore. The other thing, which I think is a bigger issue with blocking in general, is that you will be staggered while blocking on any uneven surface. Are you on a slight incline? Don't expect to block anything!
