I would like to start off by saying that although i disagree with many parts of Halo 3, it is still a fun game to play. It may not be up to Halo 2's standards YET, but you have to remember it came out just a couple months ago. It was also created to attract a larger audience full of 'noobs': bungie and microsoft wanted everyone of all skills to enjoy this game when it came out. This leaves some problems for the more serious gamers and sometimes everyone. Where to start...

1. The assault rifle should be given less range and power, it is too good to start with.
2. Melee attacks should not be based on how much shield you have, and are too powerful all in all. Go back to the halo 2 melee, minus the BxB and BxR. (I wouldn't mind button glitches personally but many others would.)
3. Ranked Swords? - The sword should be 1 shot kill in a lunge, it leaves people getting screwed over and people getting many free double kills with grenades while two others and dueling. Also, im not sure why but i can never kill someone very close up with the melee(not lunge). I do not know if it is connection,(mine is terrible), but it is very annoying.
4. Gravity hammer should not be in any playlist at all, only for custom games.
5. Put the Fuel Rod Cannon in matchmaking finally!
6. Grenades need more range, not necessarily more damage.
7. Epitaph is based solely on power weapons, I strongly suggest some power taken away from it.
8. Although I love using the ghost, it is very over powerful.
9. Bring back suicide penalty, too many losses in double team from that, and you can delevel if you really want to.
10. The Battle Rifle personally is bad-looking graphically, and it needs a little bit more strength.
11. Put in Team Snipers and ranked BTB already! I know BTB is coming in January, but snipers is why i played halo2. You can leave or remove tactical, but snipers is a must.
12. Snowbound is designed well but is played only underground. Take all shotgun/Maulers off that map and it would play so much better.
13. Don't split up the parties in BTB/Social games, I like playing with my friends, not randoms.
14. Sandtrap is not fun at all. It may be the biggest map ever, but it is seriously no fun to just have warthog fights, chopper, banshee, and one guy with a laser dropping 50 kills.
15. Take the mauler out of the game please, it ruins all up close battles. Everyone is so set on crouching with this gun and then beating you down with it. it is an excuse to hide and it ruins the play of the game(and my Kill/Death Ratio) =[.
16 You may agree/disagree with anything I have said, they're only opinions.
