I can only hope that weapon aesthetic customization makes a return and with more options. Some of the designs look great, but the color schemes just aren't for me. A black BR looks great, but that yellow streak is something I still dislike. Same with the DMR, and the scope's color makes it stand out extensively in a way I don't really like. And I can't say I favor all the navy green/beige being added to the weapons.
On the other hand, the dual coloring of the SMG in dark and light grey looks really good in my opinion; the one dislike about the SMG I have to say is that it's dotted with little black shapes in the light gray areas.
(It looks of normal size to me. Stock isn't extended, and that's fine by me, but I see no reason why it isn't extended when dual wielding isn't in play. Could it have two firing modes? :3)
I'm sure they'll grow on me, but more options in customizing is always great, and also something that can provide incentive to play.
New RPG/MAAWS weapon looks cool. Painted in a green that looks like sewage puke, yes, but looks cool as well. If the Promethean Nuke isn't returning, could this be an alternative? How does it work? I'd like to see that when the beta arrives.
I wonder how these new designs will appear when used first person. Open sight instead of a scope on the BR will take a bit of time getting used to; if we can customize that, awesome. The scope on the DMR looks a bit like an IR scope to me considering it has an added bulk and it's also featured in a different color scheme - which potentially suggests customization for the scope? - and hopefully less bulky and asymmetrical than the version that appeared in Halo 4. And the sniper......well........
I hope there isn't a tank to the right of the screen when we wield that.
