Now that that is out of the way, the game does have its problems. I'm quite sure most of what I'm about to say is well-known, but I'm simply making a list of a couple of bugs and a suggestion.
The audio cutting out. Definitely should be high on the fix priority list.
The connection problems when it comes to joining your friends Campaign servers or Challenge servers. Currently it seems as though doing coop Challenges is simply impossible. Joining a Campaign with friends seems a crap-shoot at best. This should also be high on the priority list.
The objective wheel can be pretty misleading. It seems as though "Guard X Objective" is used regardless of whether you actually need to guard it (guard = defend...) or attack. I really hope you guys implement a fix for this and make the Objective Wheel more easily understood. While this doesn't matter once a player is accustomed to all of the maps and objectives, this is a big thing to help new characters (especially if they're brand new to objective based games in general) not be overwhelmed, and downright misinformed. Seeing the wheel tell me to guard a door that I'm supposed to blow up is just irritating, and needlessly confusing. Seems like this should be an easy fix.
I'll end by saying again, I'm having a blast. This game definitely seems to have moved closer to W:ET as opposed to the direction QW:ET was going, and I have no complaints. I'm sick of seeing the game get negativity from people who were just too ignorant to know what it was they were buying. And all of the reviews that knock the game for ridiculous things such as "needing to switch classes too frequently" etc. These idiots need to just go back to the mindless Deathmatches of CoD and leave the real team-based objective gameplay to players who can handle it.
