First of all I am quite surprised you are speaking about content that literally people will be over with within today and tomorrow and not like I haven't tested it at all but I am quite honest this isn't stage where I would be bothered about balance because as I explained people will be done with the current contet you're speaking about within less than 48-72 hours from server going live.
Only want to respond to this.
That is such a bad attitude to have, as the early content is your first impression of your server.
If that feels shitty and rushed, that's the impression people get from your server and you instantly lose faith of a lot of people on your server.
Also on a balance note, people don't expect PvP balance to be 'balanced' until your core level range, but PvE should always be balanced.
