Just a random thought but, in an effort to increase healer counts and decrease shuffle queue times as a result, what about some sort of account-wide priority credit system?
Eg. If you queue as healer for X amount of matches, then you get queue priority on X amount of matches for dps specs/classes on your account, but the queue priority only applies to dps that are under or up to +100 (margin debateable) over what the healer they queued with is at.
Eg. You play 10 matches on a healer and get to 1k rating. You now get queue priority for 10 matches on your dps account wide, but only applies to dps that are UNDER the cr of the healer you queued with, +100 for margin, so under 1100 rating your dps get priority queue for 10 matches or until they reach that rating in which case it they no longer get priority on that dps but can still use the remaining priority credits on another dps that is under the cr of their healer.
This prevents low cr healers just spamming and tanking matches to gain faster queues on dps. If your dps is at 2k cr, then you gotta queue above 2k on your healer.
And while this is primarily for shuffle, I feel like many new healers that would do this at first just to get the faster queues for their dps, would end up liking playing as healer and maybe even start proper 2s/3s. Win win.
Revision. People without priority that have been in queue for X minutes cannot be skipped. In addition only 1-2 spots in a lobby can be taken by priority holders.
This should prevent any occurrence of people being skipped entirely regardless of wait time and ensure theres no issues if a large number of priority holders queue at the same time.
The concept of this is to give dps mains that are sick of queues an incentive to try out healing, or just to play their healer more if already doing so that actually benefits their dps and not their healer, since healers already have fast queues.
I cant think of any incentive besides something like this that would that would actually be enough to get someone who normally doesn’t, or has never tried, to start queueing as a healer.
For people worried about queues being longer for people that DONT heal to get priority.
This is not the case. As in order to get a priority match for their dps, they must play an equal number of matches as healer. Since there are 2 dps for every 1 healer, even with the healer then getting priority on their own dps there is still a net benefit for 1 dps for each healer that does this. So queues hopefully would be shorter for everyone, though more so for the priority holders of course.
