Dislikes:
The replacement for the grenade launcher (not sure if I should call it that)... terrible design at this point. Every time I saw it used, the slow movement made me wonder "why would I use this over a grenade?" It does nothing better than the grenade launcher in Reach in those vids. I don't care if the GL was "objectively underused" the replacement is next to worthless in those videos.
Promethean Vision - absolutely terrible. It confirms what was seen in brief snippets and expressions produced day one. Why even have walls, lets just play octagon and be done... now I can see in real time where everyone is at the press of the button, and there was no counter to it in the game play. Assuming equal skill this will end up slowing the game even more... now people will just sit looking through virtual windows daring the other to step out first... you already saw that between some of the guys in the vids... ugh.
Rockets - slower with smaller blast radius...? they are a power weapon, balance them by the number of times it can be used, location, and frequency of spawn... NOT by making them look like a missile pod.
1v1 interactions looked clunky and imprecise with the BR... I don't know if it's the recoil that we can't experience while we watch, increased capacity to strafe (from Reach), or the BR being 5 shots... but watching people nearly run out of bullets for one kill was painful.
I would prefer to not have anything moving in the reticle... but as long as shots are 100 percent accurate with each trigger pull on precision weapons... I'm happy.
I don't like how busy it looks... medals, points, notes, HUD, weapon spawn icons, grenade indicators - it's like the game is puking pixels all over my monitor.
Hate the grenade throwing noise.
Likes:
I like the look graphically. It definitely is a sharp looking game.
Movement looks improved from Reach and pretty smooth.
Hit scan weapons with hit markers.
Loving the overall variety in the sandbox with new weapons available.
Like sprint being default.
Like the fidelity of the sound overall and can't wait to hear the final product.
