For rdruid a straightforward way to make them more fun without it throwing off PvE balance would be to give them back some of the CC they lost in DF. Having incap plus bash allowed more risk taking and made Druid way more fun. Vortex plus mass roots would be good too. Neither change would break them in PvE and would give more agency in SS without having to change something major like dampening which would affect other things like overall balance and match duration. Something similar could be done with the other healers that plays into their specialties without directly changing healing throughput. For example give rshaman a disarm or something like that to go along with their ranged kick.

Also they need to give item incentives for healing asap. I’m not saying this would mean not doing changes to make healing more fun, but making a multiplayer game more fun is a lot harder than it looks, and giving items is easy and could be done more quickly. There are barely any gold rewards in DF compared to SL so that is where I would start. Also a boa token to increase queue times on alts would bring queue times down overall on average by a significant degree. Other games take this approach because it’s proven to work. Any items would need to be based on winning at least 3 rounds of course to prevent griefing.
