Well, I just started a campaign, and had the same concerns as the original poster. But I discovered that these 'broken' rules are mostly (mostly) broken combo's, and are only exploitable if the players are as knowledgable as many of the posters here.
Yes there are some powers that are too powerful, but I think the majority are only dangerous when you have certain multi-class builds, or other effects that synergize strengths. Even powerful abilities, if not used repeatedly, are not that overwhelming.
Now, I have the advantage that I am very willing to fudge die rolls, or change NPC stats on the fly to liven up the adventure. I know some here view that as sacriledge, but if it makes a better story, I am all for it.
