I kind of wish for a revisitation of tactical feats, however, with the payoff to reward tracking what happens in a round. Maybe these kinds of feats build on themselves, so the first "tactical" feat is really just kind of situational (if you don't shift in a round, gain X bonus), but the next one sort of adds to it (if you also don't move in a round, gain Y bonus) -- sort of a reward for following a particular pattern of attack that scales with how well you adhere to that pattern. Scaling complexity you can opt into is pretty OK in my book.
Trigger: PC uses an at-will in a turn, followed by an encounter power in the next turn without moving from their square.
Effect: PC gains bonuses to defense/attack/Something awesome happens!
The Player's Handbook only dabbles in this category, but some of these feats are already among the most compelling in the game. Few dragonborn characters don't consider Enlarged Dragon Breath, and I have yet to meet an elf who didn't pick up Elven Precision pretty quickly. Personally, I like these feats because they're straightforward in their effect and almost guaranteed to come up in every encounter. That means the player can understand the feat's value easily and can witness its utility often.
I really like the article and the new direction. Given that:
On the one hand, I like that there are lots of class/race specific feats to choose from. On the other hand, if I'm not that class/race, that block of text isn't useful. Martial Powers is absolute must-have for any martial class, but very few of the feats apply to more than one class and several only apply to one class/race combination. I guess that is part of the "Class and/or Race Is Important" philosophy but it does make some of the material limited in application. This is my only complaint about Martial Powers.
I found the article interesting, but the following bit annoyed me (emphasis mine):
What this says to me is that the decision isn't really in what feats to take, but when you will be taking certain feats. I'd rather see them go back to their original concept of tying race to level, and granting these abilities automatically as a character levels.
It may also speak to the idea that perhaps these feats are fairly overpowered, and should be scaled back.
