I usually go campaign with /BRD on my DRK because I am too low to hit anything to gain any valuable exp. It sucks spending my evenings, the only time I can play seeking endlessly without a single invite to show. I do ops every chance I can, I get the exp scrolls that are relatively easy to obtain and yet, it would take me months to achieve what a single night in campaign can give me /BRD. I'm sorry, but it's a glitch SE made and I'll abuse it because SE is too stupid and far too damn late to finally give some alternative methods to getting exp parties. This coming update is, much like everything SE does, a day late and a dollar short. And yet, it still doesn't remove a majority of the problems faced by exp, the party itself.
You want to complain about shit, complain about the lack of methods for low levels to obtain decent experience and you'll find a lot less people in campaign "wasting" your time. Because honestly, it's a fucking waste of mine and I hate every second of it, but I'll take what I can get.
