I like the change. I don't really mind dailies too much, but after hearing about this I won't be doing them anymore.
Pre-3.3 system had a daily rep limit.
5.2 system has a daily rep limit.
I don't see the difference? Running dungeons for rep in Wrath was just as mandatory as it will become now, if not more back then. We don't have specific head and shoulder enchants anymore. We did then.
We on the forums asked for options. Option A) Do dailies for rep and option B) dungeons for rep and the 2 options share a mutual daily rep limit. What the new system sounds is like "Bonus rep in addioton to Dailies" which is lame and will created more mandatory rep grinds.
