This game is awesome, not perfect but lots of fun.

People forget ME3 came with 5 free DLCs and lots of balance changes over a year. The game we played the last 4 years was a lot different than what was first released. Had lots more maps, characters, enemies, weapons, objective modes and so on...The 7 quick waves are a nice change but I hope platinum has 11 grueling waves...., the individual cool downs, the verticality and jetpacks are amazing....errything detonating and priming is good for team synergy... the movement system is just so much faster now...the powers of several classes are not weak (I haven't played them all), some are...

Improve the weapons a bit, nerf melee which means tweaking some tree skill, add in grab kills which were just amazingly fun, and with an expected platinum mode, new enemies, more maps and characters as we go, the game will be great. The enemies should be tweaked a bit too. The kett are the only ones really hard and well balanced. Outlaw and Remnant need some buffs and sync kill abilities. The biggest problem with the game aside from getting dropped is that about half the weapons just don't belong here and will never be used...as they are grotesquely bad. The new one they just added sucks even on bronze at level 10....no excuse for that.

But the game is already tons of fun as it is, just not perfect. The grind was just as bad in ME3 as well. 

L2P is my advice if you are crying it being too hard and if you find it too easy, just play PUG kett or take a class and guns that aren't OP. The game is fine.

Ultimately, if you don't like it, play something else...Or just become one of those COD players with 20 days playing time bitching on the mic every game how shitty the game is....Why invest time on a forum decimated to playing the game or 240 or 500 hours of your life into something you don't like?

There really should just be an official "Come here to bitch about the game" stacked thread so the forum isn't filled with the constant whining...
