Upper_Krust!
Yesterday, after finishing up some final work on my current game, I spent some thought on 4E Immortal's Math. Plugging the DMG guidelines, and the numbers from your sites' table, I noticed a slight math 'hiccup'. Monster Defenses scales ~ faster then projected PC bonuses to hit. It was a small error, but it means at the upper tiers of play that players are going to need a few more 'pluses' to hit. (On the order of about +1/5-10 levels)
My train of though started, absurdly (as usual) at level 100. A level 100 solo, by DMG guidelines, is really easy to work out, but his Defenses (AC 119; Fortitude 112, Reflex 115, Will 117) are about ~25 points higher then average PC projected to-hit modifiers.
Projected PC Hit mods:
Stat: Say base 16, +2 from race. (18 total)
- +2 per 10 levels (+20; 38 total)
- +1 to all attributes at each tier (assuming each tier is every 10 levels) (+10, 48 total)
So a maximum attribute, barring class mods (few of these I assume), is 48 - 50. Modifier +19-20.
Magic weapon is +1/5 levels, or +20 at 100th.
+39-40
+1/2 Level
+89-90
Proficiency is another +2-3 usually, plus the odd feat or two, you still end up being over 21 points (30 worst case, 27 points best case) short.
Even if you plan to end immortal's at 75th level, the problem will crop up there too. (22-20 points likely missing at 75th)
Simple solution is to work in some +'s.
As a Side note, Designing a Timelord is easy and fun in 4E, even without having to make up any new rules or conditions.
