It’s no surprise to everyone that Invasion Slayer, after 6 months of complaining, is unbalanced in favor of the Spartans. Spartans get the better weapons when it comes down to this gametype. Pistol usually trumps whatever the Elites have in the first wave. DMR is better than Needle Rifle. Shotgun trumps Sword. Sniper beats Focus Rifle. Warthog is better than Ghost. "Tank beats everything!" And this is clearly evident on Hemorrhage, where Spartans reign supreme.
Even after Bungie tried to alleviate Spartans VS Elites with “Invasion Skirmish”, it’s still bad. It’s now just more CQC based, which Spartans dominate in because they have Armor Lock and Shotgun.
I hope it is true that you are taking over Reach, because Bungie has continually failed to fix this problem, or just ignored it. However, right now the only way I know how to “fix” this is to remove it.
That’s just some food for thought. If you are reading this, thank you for reading. Everyone else, what do you think?
