IMO it's good and could be better.
The major complains are related to classes, tacticians and marksmen. Tacticians have the ability to locate in the radar the enemies. It's not a big deal for me, but when you find that almost everyone is a tactician in the enemy team it really gets annoying. The marksman uses a sniper rifle and can use cloaking, thus making camping easier (although this happens with some maps).
What's really fun is when you play in a squad with mics. The squad is more focused in the objectives, and the game gets more fascinating.
The best mode for me is "Operations".The bad thing about operations are the maps, only 3 maps... I think GG should make more maps for operations, but they said there won't be any. They are releasing a new patch this month which will fix some issues, so I hope they will consider operations maps in the future.
KZ3 is good and it can be better. There are issues, but I overcame those issues when I joined a clan.
