I can't wait for you to shut me up.
My review of the beta:
Firstly, I cannot deny that the Beta was great fun, I was totally hooked on it towards the end, especially the invasion playlist, it was a joy to play. With that being said, invasion wasn't without problems, as I feel it's unbalanced, the Spartans have a definate advantage over the Elites, particularly when it comes down to capturing the core. I believe that the main problem is the Spartans being able to spawn with Shotguns, making it extremely difficult for the Elites to even get the core outside the base. Furthermore, when they do manage to get it out, the Scorpian usually decimates them, and thus I feel the Scorpian may be overpowered in multiplayer.
Secondly, I feel like the skill gap has been reduced significantly, whilst this is great for new players, it's also slightly unfair on the loyal Halo fans. My reason for such a statement is that I feel the reduced clip size, and the fact that the DMR and Needle Rifle take so many shots to kill, makes multi-killing a lot more difficult. I'd be much happier if the DMR was a 3 or 4 shot, and the Magnum had its clip size doubled.
Thirdly, I don't feel like the rating system in Slayer Arena is that accurate, for example, a person who gets 11 kills and 17 deaths may get a higher rating that someone who gets 15 kills and 7 deaths. I feel that players should be rewarded for having a good K/D spread in this playlist.
Fourthly, armor lock usually slows the game down to a crawl, it's so frustrating to take a person's shields off, only to have them go into armor lock, and then wait for ages until they run out of power. I feel that armor lock should probably be removed from the game altogether.
But enough of the problems, overall the Beta has been awesome, the new gametypes are great fun and I hope they stay in the main game. The armor abilities weren't as broken as I expeceted (with the exception of armor lock), using spring or the jetpack adds a whole new dimension to the gameplay, and they're fun to use. Also, the new weapons and revamped weapons seem both fair and good, I'm loving the Sniper Rifle and Magnum. The vechiles have also been made easier to control, such as the Banshee, which is also good.
TL;DR: Thanks for the beta bungie, it was great fun, can't wait for the real game.
