I think WAR gets so much hate because it let down so many people who followed and defended it for 2-3 years before it finally launched. A lot were also hoping for a superior RvR experience compared to DAoC's, but WAR's RvR was a big step backward in a lot of those areas.

It might be struggling to keep its numbers from falling further, but they are at least trying their best by adding content like LotD (though I could do without the massive class changes they do all the time instead of doing small changes to see how that effects the game world).
