It's not a proc though? It ALWAYS has the TFoJ effect. Which is basically the same as generating a HoPo, except that it's not subject to the cap, so you can still Judge at 5 without being sad. Seems OK to me.
Essentially, the new T21 bonuses are almost an exact replacement of our T20 bonuses, just being Judgment-focused instead of BoW-focused. Boring, but fine.
The equivalent of one holy power every judgement is garbage for a 4 set, really hope it doesn't go ahead. The 60% judgement is fairly strong when combined with the aura and mastery buff, and I can imagine mastery is going to be on par with the other stats to a much greater degree than it is now.
Previous iteration of the set bonus sounded much better to me. However, as soon as it was up on the front page people cried bloody murder and bitched about it too. So, idk maybe we could just wait and see how it does in practice rather than grab pitchforks and get bitchy immediately after Blizzard even says "Retribution"
