I don't think any of those are really a problem. Who cares if I can't name my characters or put the Doom skin on? And you only have to unlock the attachments once, so I don't see why it matters.
If I had to pick the things that are most annoying:
1. Unless I'm missing something, there's nothing in the game that tells you what capturing a health or supply command post actually *does*. You have to work it out for yourself. Same goes for Molotov Cocktails.
2. Needs more parkour maps (DLC will fix this, hopefully). They've made the game hard enough to get into as it is, so it would be nice to have some really high-level parkour stuff.
3. No symmetrical objectives, i.e. capture the flag, control point style missions, bomb the opponent's base, that kind of thing. Everything is asymmetric at the moment. I think it would really pick the game up if it wasn't always attack / defense.
4. Playing as Security on Shipyard is just [censored]. I'm going to keep making posts about this until they sort it out. I even emailed them, but haven't got a response.
5. No weapons testing area. It'd be nice to have a shooting range that let you work out which guns / attachments you liked best
6. No lobby system.
7. Medics being able to revive someone repeatedly makes offense extremely difficult at times (see point 4).
8. The bots' bizarre priorities i.e. placing turrets in places where no-one ever goes, going for supply command posts when you're hacking, never putting mines in sensible places, etc
9. Again, unless I'm missing something, nowhere in the game apart from the tips database does it tell you that you can kill a downed enemy by walking over to them, looking at them, and doing a meleƩ attatck. It also takes a stupid amount of ammo to do it from a distance.
10. Hacking usually takes too long and Engineers remove hack-boxes far too quickly. Either speed up hacking or increase the time it takes to remove a hackbox.
That's it for now.
