take ten isn't going to cut it when you are facing a -8 to your balance check (-6 for full plate, -2 for heavy steel shield). The unrushed defender is going to fail their balance check 40% of the time! Gotta suck if want to actually force the action and fight your through the attackers. Especially as Balancing negates any Dex bonus to AC in the first place.
So, I guess you are conceding my point then? Because at some point in this thread, the focus of the argument went from, 'Fighters who wear light armor are unfairly screwed by the RAW so we need house rules to help them out' to now, 'Fighters who wear heavy armor are unfairly screwed by the RAW so we need house rules to help them out'.
And my point all along was that one only needs rules to help out characters in light/medium armor because one has defacto house rules that remove the drawbacks to wearing heavy armor.
I have no need to argue with you over whether your house rules suit your game better than than my house rules suit your game. If you don't like the idea of fighters in heavy armor stumbling around on difficult terrain, that's fine with me.
No, its pretty simple really: the stairs were merely spiralled in such a way that the shield of the attacker couldn't be brought to bear effectively in the stair well.
Well, to begin with, no, that's wrong. The stairs were spiralled in such a way that the sword of the attacker couldn't be brought to bear effectively in the stair well, which the d20 rules quoted above actually attempt to model correctly by giving the higher character a cover bonus. And secondly, the stairs in a castle were also deliberately made uneven so that a person not familiar with the differences in heights would misjudge and stumble on them. Or in game terms, they deliberately designed the stairs to give an attacker a circumstance penalty to balance when using them above and beyond what stairs already give. They wouldn't have bothered doing that if stairs weren't a significant obstacle to begin with.
The stairs weren't the hazard you are making them out to be. Yes, they provided the defender with a small advantage; no, they weren't as difficult to negotiate as the core rules would have us believe, with defender and attacker alike stumbling around dangerously.
Which is a complaint that amounts to, 'How difficult should the balance checks be on a stairway be realisticly?' That's an entirely different thread than 'What can I do to fix the fighter?' Returning to topic, I don't believe 'Make fighting in light or medium armor viable' is really a concern, because it already is if you bother to make use of the skill rules.
