1. I am so sick of seeing posts like these. They're everywhere, there's no need to post another one.
2. Weapons- Some weapons are overpowered, but they're all balanced. Like the Incineration cannon having to reload after every shot.
Lag- Every online game you play is going ot have lag, there's nothing you can do about it, so why complain?
Hackers- I have never experianced anything you described and I am SR-118
Maps- The maps aren't the best in the series, but they aren't that bad. The only map I have an issue with is complex.
Forge- No comment, I don't use forge so I don't know if it has any issues.
Weapons/ vehicles- Multiplayer is just a hologram/ simulation maybe they don't want the other stuff but a flying unsc vehicle would be nice, and for the smg issue, the suppressor is pretty much an smg.
Armor- If you want to wear the armor in Reach, then go play Reach.
If you hate the game so much, don't play it. nobody is forcing you to.
