That doesn't really follow, actually. Yes, level bonus outstrips stat bonus. This doesn't mean that characters, over time, become more equal in their ability to hit regardless of their original stats. They will be less divergent than in previous editions, but that just means that no one will be worse than they were at level 1. They'll still be just as bad.Yes but also by that level (30) you should have some magic items that would fill in the other 12 rounds of combat. Not to mention your daily powers. I agree, the advantage of 4e, "EVERY CLASS ATTACKS THE SAME" and this is how this system will work. As you go up in level your level bonus will out-weigh your stat bonus (in most cases). The characters will be much more potent with a weapon than in previous editions. This really starts to separate around paragon tier when the level bonus begins to outstrip the stat bonus.
In short, if my attack bonus at level 1 is +6 and yours is +4, the absolute difference is 2, and that's what matters. And at level 10 if my attack bonus is +11 and yours is +9, the absolute difference is 2, and that's what matters.
Most experienced min maxers do not feel that a 20 is always the best choice for the majority of characters. An 18 created with a 16 +2 from race is usually superior due to the high cost of buying a natural 18 using a point buy. A 16 is considered slightly less useful, but still viable for many builds, though certainly not optimal.I agree it does cause a bit of MAD. Here is an interesting thing though. 4e is all about maximizing your one stat 20 nearly all the time if you have to go 18.
This really isn't the case. The difference between a 16 and a 20 is going to be nearly the same in either system. You'd have to do some really, really extreme things to the internal math of the game to make that no longer the case. Plus, "good enough" is a relative concept. You can't make a 16 "good enough" for a guy who could get a 20 if he wanted to, because he's got the 20 available as an option.If you introduce MAD, this may be a little difficult for some to ponder, you actually lower the arms race for everyone including those that have to focus solely on a single stat. If a 16 is good enough for one character it can be good enough for another - including the fighter who only really has to focus on a single stat. I am not saying that every fighter will be made like this but they could be made like this. In this case MAD, may actually may be good for 4e.
There are a few changes to the internal math that could counteract this, but they're awfully extreme. Like making a 16 allow you to hit on a 3+ or so.
