Wow... I have never seen such an evenly divided poll! As of this writing, it's 38 votes for "no spells while in armor", 40 votes for "arcane spell failure chance" and 41 votes for "cast freely in armor".
If the broader gamer population is so evenly divided on this question, it will be tricky for WotC to make these rules appeal to everyone.
Its sorta even. The result is skewed by the nature of the options. I put "no spells in armor" and "armor chance of fail" in the same conceptual category as it indicates no free ride for arcane casts with armor.
The way I see it 58% (current number) of people dont want arcane casters to be unhindered in their ability to cast spells in armor, with 31% wanting it.
