Since the multiplayer update, I’ve made a couple characters that are purely support builds, to help my friends level, heal them, etc… It’s fun to play support now that multiplayer is implemented!
One quality of life suggestion I would make, for healers, is the ability to heal your friends by targeting/clicking their party portrait, in addition to being able to click their character. I don’t know that this is easy to implement, but it would be really helpful because it’s tough to see where your friend’s character is sometimes. This is a feature in WOW that really is helpful, and I find myself wishing we could do it in LE as well. Just makes healing easier.
