Queue times are pretty long for rated solo pvp. Miserably long in fact. One of the most “quit” moments is being in a for 30+ mins that said it would be a 10 min queue and getting absolutely stomped so you get functionally nothing. And in this environment your individual performance may not be a factor. That is to say that no matter how good you aren’t the outcome wouldn’t change.
I think giving a bonus to earned honor and conquest proportional to time in queue above the expected time would help. If you’re interested in participating in a specific form of pvp the terrible reward to time investment can seriously discourage you. This can create negative feed back where people just don’t queue for that mode.
If queue times are being negatively effected by a lack of specific roles incentivize them via rewards. I don’t mind if Healers are getting extra Conquest if it means my queues are not half an hour long.
It seems like a lot of issues in pvp are eco-system issues. Not having enough or the right balance of players so I think issues of inflating economies around honor and conquest are worth it.
