I don't hate Tau anymore, but they annoyed me for a long time. To GW's credit they didn't release too many new army factions / races over the years and have kept it reasonable. We could have been inundated with hybrid animals like lizardmen, space skaven, etc. I'd still like to see AdMech, Rogue Trader, and Genestealer cults as proper armies, even within the same book.
This is a great looking army! I'm lucky to have seen it in person a couple times. I love themed forces.
