1. Remove Champion System and Veteran Ranks. Make everyone level 50. Remove Cadwell Silver/Gold and the whole concept of questing for another Alliance. Strengthen faction identity. An AD character entering Stonefalls, for example, should be considered a hostile act and the town guards should respond accordingly. Allow for opt-in PVP (i.e. flagging yourself) for players who wish to defend their homeland.
2. Get rid of gear stats in PVP. Make your stats be based around your "spec" (your 6 slotted abilities + weapon type). Balance classes and abilities around this much simpler system. Tightly control time-to-kill by both limiting burst damage AND mitigation/healing (with larger health pools instead) thereby ensuring a 1v1 lasts more than 10 seconds without potentially becoming endless.
3. In PVE, get rid of 5-piece set bonuses. Repurpose some of the more interesting bonuses to show up as an effect on a single piece of gear. Limit this to helms, necklaces (jewelcrafting), and weapons only, thereby allowing up to three bonuses on character at once. Implement the tried-and-true Diablo style loot system. Something drops, equip it right away, become more powerful, rinse and repeat. Ideally you would want to see a new upgrade drop a couple times per week of normal play (2-3 hours per day).
4. Make a separate resource for dodge/block/breakfree/bash/sprint/sneak. Equalize the damage, cost, and regeneration rate between Stamina abilities and Magicka abilities. Give more abilities cast times and, most importantly, only allow damage to actually go through at the END of the cast time. If you cancel out of a cast time (aka the animation) it should also cancel that damage.
5. Introduce dungeon "seasons" whereby the Normal Mode gear of the current season is almost as good as the Veteran Mode gear of the previous season. These seasons can be three months long. This would provide a natural catch-up mechanic for new players. Dungeon bosses would become more difficult each season, but there would be other catch-up gear (equivalent to last season's Normal mode) available outside of dungeons (world drops, crafted).
Anyways, these are just some of the ideas I think would strengthen the long-term health of the game. I don't expect any of these things to ever come to pass in THIS GAME necessarily... it's really more just a general list of good game design practices we should expect from future MMOs if they expect to retain and grow their playerbase.
