I've had a chance to read thru The Tunnels & Trolls 6th Edition (unauthorized) and there are bits I'd like to steal in whole, and other bits I'd rather balance out.
I never really liked the doubling of armor for warriors, as it wasn't level based, and I felt it should be. 6e makes it a straight +2 armor points per level instead of the doubling, which is a major powering down, especially at low levels.
At the same time, 6e ramps up the combat adds for warriors at an immense rate. It adds the new level to the previous level as combat adds. So the progression is +1 / +3 / +6 / +10 / +15 for the first five levels. +21 / +28 / +36 / +45 and finally +55 at level 10. It get's even more unbalanced at higher levels. In 7e, the combat bonus at level 10 would be +10, as a ground zero reference point.
What I would like to propose for my house rule would be to use the same progression for both armor points and combat adds. It would be +2 per level for the first 5 levels, +3 per level for levels 6 thru 10, +4 per level for levels 11 thru 15 and so on.
This gives us a progression of +2 / +4 / +6 / +8 / +10 for both armor and adds for the first five levels, +13, +16, +19, +22, +25 for levels 6 thru 10
Overall it balances out the curve of the combat adds progression, while advancing the curve of the armor points slightly.
