hazards bot base works fine . . . but I don't notice any significant difference vs enyo (which was also free). Vitalic also has a very nice light weight raiding bot base which comes free if you happen to have his rogue routine.
my issue atm is there is no good hunter routine for high lvl PvE.
tuanha's is ok for low level PvE, but just for instance(s): 1. you cannot disable Chimera shot and you have to for gorefiend mythic (or you will get kicked from raid) and 2. it is still not tuned for HFC 4 piece and 3. it fires barrage at single target (any other MM hunter will ask you WTF if you do that)
It's interrupt and traq settings are very nice, as are the trinket usage options, and the auto targeting works pretty well . . . but the above basic rotation flaws make it essential unusable in high level raiding.
Pre ban wave there were some other routines focused on hunter PvE (Huntastic for instance) but they all seem to have been discontinued with no maintenance after the ban wave. (I have bought and tested every hunter routine that's been available the past year).
