Oneof the things I was disappointed with when checking out the grove is how poor the tutorialization of the quests and events are. Moreso that some of the quests are actively going against what you'd do in normal content.
As an example of a tutorialized Event there could be a small chain of events or quests that goes over marking targets for interrupts.
Quest 1:
The target needs to be interrupted twice and you get and NPC to tag along with you. The NPC will auto mark the target and it should be setup where if you interrupt while the NPCs interrupt is available it fails the event (or maybe just full heals whever your attacking). Which would teach the player to prioritized cyling your groups interrupts.
Quest 2:
Same deal, but now the NPC wont interrupt unless it can see your interrupt on cooldown on the target.
Just some quests like this. Maybe refined a bit, but this is an ideaI came up with in like 15 seconds so I am sure with more thought it could be better.
