HOing: Preferably avoidable, especially because I can't hit squat so always lose.
BnZ: Just ignore the Spixteen whiners who are mad because you won't bring your poorer-turning plane into their circle of death, and fly YOUR plane the way it needs to be flown,
Roping: Are we talking the usual LA Ho'n'Go, running for five sectors then turning around when the guy chasing you gives up, or duping a guy with low E into following you through the vertical and killing him when he hangs himself on his prop?
The former IS annoying as all hell and anyone who practices that cheeseball "tactic" deserves the Ch200 drubbing. The latter, however IS perfectly viable and is part of energy fighting, so see my remarks on BnZ.
Running into the Ack: If you're one guy against a horde then YES it's viable, but in 1vs1 fighting there is NO reason to drag a guy into the field ack or through a gauntlet of Ostie's and M16s.
