I am a long time player of mp and it was about all I used to play on 360, and I consider myself using guns over powers 90% of the time. The weapons update left a lot to be desired. While I feel like they are on the right track with bringing some of the weapons up to the point of being usable, they are still missing their mark to me. While weapons have generally been a little more useful, weapons like the halberd still feel slow and generally not worth using over weapons in the same class.
ME3 weapons generally all felt usable at almost every level of play given enough skill as the damage was adequate enough to not drop off. I have not gotten a same feeling from Andromeda. I have noticed that the hit-boxes of units seem to be very particular in this game, and I feel that I typically have to aim for the top of the head rather than the face to get a head shot. I would like to be able to use the mattock and halberd in much the same fashion as I did the harrier in ME3, but the halberd feels more like the common version of the mattock rather than an upgrade. It shouldn't take 4-6 rounds with a Level V halberd with a lvl X on a lvl 20 soldier to take down a wraith on bronze, especially since it's rate of fire is depressingly slow.
I find myself still leaning on the same weapons that I was before the update, which I would like not to be the case. ME3 gave us the Valkyrie, which, in the original multiplayer, did not have as high a bounce, or as slow a rate of fire. If I am getting an ultra rare weapon, It should be far superior in all areas from a common weapon.
Rare packs in ME3 gave us broken stuff like the geth shotgun, they didn't patch it, it was left broken and epic. Even compare the Soned as an ultra rare to the Typhoon in ME3. The Soned is a strong but cripplingly inaccurate weapon, vs the Typhoon, that gains even more accuracy when shooting behind cover, auto pierces, and has a massive damage output. Generally, I am glad I am able to use some of my old favorites in this game, I just wished they felt as good as they used to. I miss being able to mow down 10 cannibals with a typhoon and have piles of bodies under my N7 destroyer. I miss being able to take off heads like a shooting gallery with the M-99 saber.
