I'd personally like 2 things to change with this:
#1. Change up the role requirements for dungeons. Allow for 1 tank 3 dps compositions, 4 dps composition, 1 healer 3 dps composition if you WANT. I'd like to see this as an option for those that are open to trying it. For instance, many trifecta achievements are run with 1 tank 3 dps. Many normal dungeons (pretty much all) can be done with 4 dps. It would solve the irrationally long queue times for dps. If you don't want to do that, you would leave it untoggled, but there should be ways around such a long queue. This is not to necessarily force everyone into this, but more to have these as toggleable options if you yourself would be okay with one of these 4 compositions i've listed. Again, to reiterate:
Classic 1 tank 1 healer 2 dps
1 tank 3 dps
1 healer 3 dps
4 dps
#2. Add a normal arena finder as well - heck, i'd even be down for a veteran arena finder (it'd go about as well as most veteran dungeon pugs go). Dragonstar arena and blackrose prison are 4 man content options. Why not include these in a finder system? nDSA and nBRP are not more difficult than DLC dungeons. I know a trial finder system solely for NORMAL trials is a bit more controversial, but i'd be fine with that being added as well. Craglorn is in and of itself almost a group finder, but it'd be nice to have these as options so you don't have to camp out in this zone. You can quest, do housing, craft, etc. while waiting on these other content options.
Just my thoughts
