I'm on board with this. I remember awhile back when SE was wanting player feedback about the jump potions I wrote a really long peice (like a full page and a bit long) in detail with all my thoughts and opinions on the matter, but when I came to post it, surprise surprise "Your post is too long, please edit this to be short enough to water it down so much that it becomes worthless kthx." At that point I got super cranky and was like "you know what **** it, here's a link to a google doc with the post I wrote, if you care about my opinion devs you can look at it, because I'm not cutting out 80% of what I said because I have a character cap - if you ask for feedback, don't cap how much we can give."

As you can tell i'm not at ALL salty about that :P
So yes i'm totally on board with this, it's just such an unnecessary restriction.
