If you want us to spend money on, or grind for dozens of hours for, these Locust skins and characters, at least let us use them in both PvP and PvE.
None of the old excuses work anymore.
“It will confuse players” was, firstly, an insult to the intelligence of your fan base. Even when Locust were the primary enemies, this excuse was pretty lack luster, but now it’s just nonsensical. Plus, friendly fire isn’t a concern in these games, so even if players were to get temporarily confused, the consequences would be minimal.
“It goes against the lore” doesn’t hold water either. Not when we have two Spartans, a grandma, and an androgynous cyborg, from different universes, in all these modes already.
“They don’t have skill cards or voice lines for these modes” Then make some. You already waste time adding expressions to these characters, it wouldn’t take much more effort to add PvE voice lines.
Bottom line is, there’s no good reason to not let us play as Locust characters in horde and escape.
