f.) Healer no heals, only damage- For a long time, SE has had trouble balancing healers, giving them a true healer role with how this game has shifted and with how much damage is valued, and how little healing is inside endgame content. To ease healers of their responsibilities, and to force a more healer-centrist role to them, they have limited their damage rotation and added more overall healing. I believe that healing and damage should be combined as one similar to sage, and for most abilities, healing being dependent on damage in some way. We have this in a small complexity with the giant star fro astro's, affestus(lol) for white mages, sage for its obvious skills. This would give them some identity, and depth with the only pure healing they have being a HoT, a shield for mitigation, maybe an oh shit button like they all have, with al their other abilities contributing to damage. That, or forgoing the healer role entirely and letting every job heal themselves since healing is rarely needed, specially outside of endgame content (I 3DPS, 1 WAR dungeon runs all the time).

Exploration Content, crafting- This is my favorite content, exploration. I still think Eureka was the best in terms of exploration but Bozja and Zadnor have the best in combat, specially with the duels. This time around, the Crescent Islands are pretty bare bones as is he Space Exploration content. Now it is to early to count them out entirely right now, but i feel they're both lacking and are a bit of a missed opportunity. I had a thought though, why aren't they combined? One very large map that is filled with battle content, CE, Duels, a qeueable dungeon/raid, but with the crafting and gathering fates seen in Space exploration, and the structure building done in the hub of the area and have the 2 synergize? They could release the content with the crafter portion released first, let them build the hub area and gather basic things and doing the dily crafts the way they are now, then release the battle portion, having the area specific armor be crafted by other players in a recipe requiring battle only items?
