I too got a hold of the new books via pdf, and they are amazing. Every Character gets to do three actions like a three act play during his turn, a standard action, a move action, and then a minor action. Clerics and Warlords do their healing (inspire healing surges) during their minor actions, so they don't just have to be the healer anymore, which is cool.
The game also introduced stages of woundedness, when you get to half your hitpoints you are "bloodied" which has it's own set of ramifications both positive and negative.
I love the new Warlord. My first character I just made yesterday was a Half-Elf Warlord, and I used my first feat to multiclass as a Warlock to gain the Star Pact power Dire Radiance (I can basically bring down the astrolgoy star power in the midst of battle), also as a Half Elf you get to be a dilatante which means you can choose another's classes At will powers and make it into a per encounter power for you. I chose another from the Warlock their Eyebite power which is like a mini mind blast and vanish for one round to the target you mindblasted! Then, also at first level you get your three main class features, plus two At will class powers, one encounter power, and one daily power. And these powers are not necessarily spells. For instance the warrior types have the martial power source, so their powers are called Exploits, like combat tricks, tactics, stunts. So it's cool. The Warlord is a master of getting everyone in position and gaining combat advantage through flanking. He is great at inspiring others to to better to, but only if he can kick arse in the first place. My daily power is Lead the Attack, which you would use against a boss character, cause if you hit you get tripple weapon damage and your allies are then +4 (I have a high Int and tactical presence) against the same target. At level two I'm going to get my first utility exploit which for me will be Knight's Move, which allows me to point and give my move action to an ally as a free action, more positioning.
The cool thing about the game (even though it does seem like the battle rules are a glorified polished miniatures game) is that I can't wait to see how a party with all these weird and cool abilities learns to use them in concert...wow! It's going to make for some amazing combinations and team tactics for sure, something like no game has ever had before. And the actual role-playing, well the quality of that depends on the quality of the DM (his running of NPCs and adventure design) and the quality of the players to actually be involved, so that is system nuetral as far as I am concerned.
And the new Skill Challenges are amazing for facilitating role playing too. The Dm can design Skill Challenges that have you making multiple rolls over time to gradually build success before failure strikes, should be great fun!
Overall, from reading the books for three days now, I'm so psyched to play, and the new system has me buying a new computer and setting up CC3 to map the local campaign area, and it's so exciting again!
Can't wait to play with my table top group, but also can't wait to play online with people like you through the new Virtual 3D game table with chat!
Woo Hoo!
