You need to make full use of you character and get wow gold.
I find it highly unlikely. Blizzard may revamp some of them, like what was done with Shadowfang Keep and The Deadmines, but there really isn't much point in adding more content to the earlier levels of the game. As was displayed very well with Cataclysm, you need to fix up your really ancient content to woo new players, but the vast majority of players don't really perceive low-level content as content. Most long-time players blaze past it so fast that it might as well not be there at all.
On the other hand,making sure there is enough content at the level cap is what is most important, because it gives players something to do when they hit the end of the road. Cataclysm quite notably did not have enough such content, because the low-level content revamp took so much of Blizzard's energy. The revamp was badly needed, but level-cap content certainly took a huge hit because of it.
In my own opinion, my paladin is going to wear Lightbringer, which is tier 6. While Tirion Fordring left a black mark on that set during Wrath of the Lich King, it's still one of the best-looking armor sets in the game, I think.I don't agree with all of the people that say Judgement was the only good paladin set. The Justicar set is simple but strong. Lightsworn from Icecrown Citadel is pretty good. I actually ended up liking tier 11's Sapphirium. Crystalforge can actually look great on Draenei ... but only Draenei. You need to make full use of you character and get wow gold,levels and all wow gold items,at the same time,enjoy the process.
