I greatly agree with visual effects on buffs/debuffs. If I'm taking bleeding damage, I'd like to bleed. If I'm cursed, I'd like at least some kind of faint aura.
One thing I actually would like to see from vanilla WoW that it later screwed up is the waypoint travel. I hate instant travel, and would much rather see myself going across the countryside. This is also an important part to gameplay as well. When you're forced to experience the world itself, the world becomes important to you, and you develop a reason to fight and adventure. I believe it's WoW's inclusion of far too much streamlined content (more teleportation, instant dungeons) has made the content a meaningless chore than a fun experience. Whereas once, doing a dungeon was an exciting break from monotony, now it has become monotony. Whereas questing once brought factions against each other and developed factionalism among players, now there is little meaning to the gameplay.
The more accessible and streamlined the world is, the less real it is.
Man, i played WoW and I cannot agree more. The game should let you explore the world, not instant teleport for everything... I think if they can reduce more that teleportation thing, rarely u use teleport for something, i think it could be better. If they dont implement taxis on the game, then it could be even better, Neither fly mounts, thats screwd up all pvp world in WoW, dont let that happen on TESO

What they could implement is something like GTA. When u die u apper in front of the hospital, in TESO they could implement doctors in all the citys, villages and some walking in the roads, when u die u appear in front of the doctor near of corpse. And a option like appear in 4story/Meting 2, that u can ress in the middle of some city near you. But i dont know if that are good ideas. But thats only to avoid camping...
