Interestingly enough, the most valuable tip I got in AW3 is as applicable to AH as it was to AW but for different reasons.
Let me tell you, hands down, HTC has always had a much better data transferral than AW did. Latency was a more discernable difference way back when.
The advice was simple, start a lead turn about 1 - 1.5k out, of course doing the dive for merge speed if possible. What this often did was put me on their 6 after they blew past me. In AH it's still doable but I'd start it in the MA around 800-1k out (to avoid the HO) In the DA where the unwritten rule is no ho on merge, you can cut it closer in to about 500yds, with the same result, pulling into an offensive position.
I much prefer HTC's implementation (and it took me a few months to adjust after coming over from AW3.) I can't HO very well, heh, never could, but there are times when it's simply the shot to take.
ymmv
