PArdon me? when (exaclty did baratheon have thier day? it must ahev been pretty short - becuase msot fo us sure missed it. Lannister has been dominant since the game re-booted and Martell has been good since Prices hit - and now they are spectacular. So - I think your conclusion to your post is way off.
As to vigilant - true. But you're ahrd pressed to find playable Vigilant characters with inherent renown. Most Vigilance has to be given e,g via Bannerman what would make the glass cannon a little higher caliber is a way to get some of these non unique, vigilant characters the hitting power they need so baratehon cna close a little better.
That and Burning restricted.
Its funny - i don't mind the matchup with Lannister. I really feel I cna beat them givne decent draws for both of us out fo the gate. But Martell...i ahve no confidence. I have to strip away clser cards to laod up on event cancel just to have a shot, adn even then - if it goes past Turn 3 i knwo its over. It just doesn't seem fair against Martell. The Lannister matchup is tough, but fair.
