You seem to dismiss the usefulness of Macaroni +1 though Asdrabael. Tyjet doesn't even have a Hauteclaire first off. So what should he use? A Company Sword is the highest base damage sword in the game in a full party. Would that serve him better?
Or would the +4 enmity help him? In this particular situation, since he idles in Homam due to his healers lack of skill/blink-me-not, Machete +1 will give him more enmity overall to play around with.
So what's the point here?
The 4 enmity with the added negative impact of -4 accuracy and sh*tty damage makes it really not a very good sword if you can get better alternatives like haute for non-atonement situations.
That's the point, what's the alternative to someone who doesn't have a Hauteclaire? Most likely a Joyeuse, but Joyeuse isn't the be-all-end-all answer and Tyjet feels he needs more enmity in his set. Also, Macuahaitl +1 has 2 more base damage than a Joyeuse anywho.
So I see no reason why +4 enmity, or +4% enmity, is such a bad trade-off for 1-2% less acc on something you're never going to cap your acc on anyway.
Also, not everyone uses windower or even plays on PC, so you can't always count on people to use super windower macros to switch out every single piece of gear to maximize their performance. It'd be great if we could but that's not realistic.
So as such people like me who play on 360 I use somewhat of a hybrid set like Tyjet does so I can crank out a bit more enmity out of my TP set because I also don't have Atonement, and every bit of enmity I can get is more flexibility for my Alliance.
