They do from talents and abilities. Lowbies may need a bigger boost than they get right now because they're very limited.

Brackets are a horrible idea for two main reasons. The Queue should be the most obvious. The other seems well enough solved by Bioware with the Bolster system. I'd rather see tweaks in the Bolster system so a well played lowbie can still challenge a maxed out character. Over time, they can make improvements, like increase how affective stats are for lowbies. I don't know how much of a difference PVP gear makes, but obviously talent and ability discrepancies are an issue, so if things "normalize" by level 30 and start requiring PVP gear by level 50 to compensate for those disrepancies, I think we'll be ok. Queues were HORRIBLE in Rift, and they'd be horrible here for much of the same reasons. The bolster system solved the need for brackets. We should improve it rather than get rid of an excellent feature.

So, let me get this straight, you're upset that there's fluff in the way of your questing when the game practically from day one marketed this as a key feature? If you're seriously upset over a game's KEY FEATURE and actually demanding they change it, I have only these words to say to you. In fact, I'll let Jay & Silent Bob do it for me: http://www.youtube.com/watch?v=D2TbE8uHOJ8&t=0m17s
