I love the books. Honestly, they are why I am such a huge fan. Another person had it right when they said that the EU (which by the way guys, The Old Republic is a part of the EU) is one of the main reasons Star Wars exploded and became so popular. Honestly, try and think for a moment what Star Wars would look like if there was no EU.
I also understand that not everyone enjoys the books. That is fine. Everyone is entitled to their opinion. But just remember, that is all it is: an opinion. Just like my reasons for liking the books/comics/games is based on my opinion.
As for the statement that Star Wars has too much war (seems kinda ironic, eh?). Some of the wars are not "OH MY WORD THE GALAXY IS GOING TO DIE!" However, the New Republic (now called the Galactic Alliance) is the major ruling body in the Star Wars Galaxy. Any threat to them, or a planet belonging to them, is going to handled by the Jedi and the Galactic Alliance. However, there are also other governments in play, which the EU states clearly. Such as, and not limited to, Hapes Consortium, Chiss Ascendancy and the Imperial Remnant.
Also, look at our own planet, Earth. When was the last time we had ten years without a war of some sort. Now just imagine an entire galaxy of planets...of course there will always be conflict.
With saying this, and I say this with a heavy heart because I love Star Wars...but if the new trilogy does negate the entire EU...I don't think I could enjoy it.
