Granted, it's not all luck, but for someone as unskilled as me at long-distance tags, it sure felt lucky. As for you, you've got long-distance tagging down, even to the point of tagging Banshees from behind as they head on their merry way. I still have to finish polishing my regular tagging, and maybe set up a nice Banshee Battle, though unfortunately I've only even finished Halo (the level, not the game) on Heroic - Legendary was a pain even on Pillar of Autumn, and I only managed it once (as for Heroic on PoA, I can do KTA, No Health Lost runs quite often). As a result, I may decide to split the Marines into a few locations; half at the end of the stream, for instance, and then maybe half on the cliffside hilltop. Then I'll have an excellent save that's not too easy and gives me options.
