In base defense "High" often, to me, means co-alt with me as I always tend to climb when ever I have a chance while alot of other pilots stay low chasing vulchers.
In transition to a enemy base "high" often, to me, means higher then me. Not because I fly low but because it truely is a high alt target.
In fights over enemy base it depends on the situation. If its a fight where vulching has started then high means co-alt or lower. If the fight is still going on then it most often means above me or co-alt.
Im not saying Im an alt monkey but I do want to have alt in base defense and in CAP situations to take on enemies that come from another field.
