TBH I don't know why there are so many Steizerisms* if:
1. There is a medal for everything
2. Phrases like "King Still Leading!" are glaringly obvious to a player, but perhaps I'm holding the intelligence of the general populace in too high of a regard.
2a. If there isn't a secondary weapon indicator because of loadouts, why can't we let players interpret medals using the Post Game Report that
EXPLAINS EVERY MEDAL WHEN YOU HIGHLIGHT IT. That seems more sensible than having Steizer say a bunch of obvious crap.
2b. Waypoints. Over. People's. Heads. Situational awareness people.**
Then again, I play FFA Oddball matches where people fight each other instead of jumping the guy with the oddball chillin in the bubble shield.
The king announcements seem to serve a similar purpose as the CTF announcements - to constantly jostle the memory of participants. I enjoy KotH and rarely lose, and I can tell you right now, there's been quite a few wins where you can see people just end up getting mad at each other and playing slayer, and they forget it's KotH until the announcer reminds them I'm 30 points away from winning.
Hopefully they can adjust the announcements post-ship with Megalo, much like Bungie could with Reach (I'm pretty sure Megalo controls the announcer for most things in Reach) if they feel they overdid it.
I can tell that's the impetus behind the announcements; see the edit above. It just seems a bit too redundant, comparable to MW2 levels of UI overload, but at least in Halo 4 it seems more conducive to gameplay.
