-Destroy a Banshee (three times)
-win three games of total control/slayer/ctf/one-flag/oddball/etc
-kill 10 spartans with fusion coils
challenges like these…why. These are so specific and require more luck than challenge. (as for the mode wins, its an issue because it feels like a lottery just to get the desired mode and even thats not a guarantee because you still need to win the match)
The banshee one is a pain because after about ten games of BTB Ive only ever saw a banshee twice and both times never had a weapon that could wipe it, I have however easily killed over four wasps, so why couldnt the challenge have been destroy three aircraft? As for the objective modes instead of randomly choosing one, it should have just remained vague (like win three matches of PVP, which already exists of course but at least thats less asinine.)
