This expansion introduced two major changes to the PVP system, honor talents and gear scaling. Personally I welcome both these expansion changes, alone. But introducing both of them at the same time defeats the stated intent of gear scaling.
What do I mean? Well the intent of gear scaling was to make it so that new PVP players and old players have about the same "power" regardless of gear. The idea was that people don't have to feel left behind by showing up for a BG in ilvl 820 gear when the rest of the bg is wearing ilvl 870. Everyone's gear would be roughly equal, and therefore the battle would be more about skill than gear.
That's good, but with the second change, introduction of honor talents, which are gated behind your prestige level, they have largely eaten away at the advantages of gear scaling. Now a new to PVP player can jump into a bg and while gear is roughly equal, the lack of PVP talents means they will get smoked by experienced PVP players with all their honor talents.
Of course the new player can keep progressing until they get the talents too, but it's a long grind to make when they are so under powered relatively speaking.
So my point is they solved a problem with one hand, only to break it again with the other.
I'm not sure what the fix for this should be. Maybe they make all of your honor talents available immediately, but to reward prestige they give other rewards (better gear and AP per match for higher prestige players)?
