Some replies on 4th ed

After posting a message about the 4th ed experiment on RPGNet, I did get a couple of replies that clarified two things for me:

• When you gain a new level, you can choose between taking a new power/feat OR replacing one of your already existing feats with an improved version of the same feat (like Toughness -> Improved Toughness).
  
• There are a couple of ways for a character to help another character make a save. There is a 1st-level cleric-spell that can give a character an extra save, and the Heal skill has "grant a saving throw" as one of it's uses.
  

The last point makes the following scenario possible: Kazakh the fighter is severly wounded, and is hit by a Blazing Skeleton, that set's him on fire. He only has 3 points left, and he knows that he propably will get more damage than that from the fire's ongoing damage.

Luckily for Kazakh, his mate Tardan the Cleric is nearby, and Tardan acts before Kazakh. So, Tardan rushes up to Kazakh and Heals him, so that he get's an extra save. Both the Heal-check and the Save succeeds, and Kazakh is once more grateful that he isn't alone on this.

This only goes to prove my impression that 4th ed is even more about Group play and coorperation than previous editions.
