Major -
1. New Races (5 years since last faction specific races) (Personally I would like to see either something NEW or ethereal/naga or ogre/akarroa)
2. New islands / Revamp:
South Kalimdor(Barrens, feralas and down, Feathermoon island has been fortified by the alliance, theramore rebuilt, meanwhile ratchet has been claimed by the biglewitle cartel, and goblin miners have blown through the mountians to create a “panama canal” into thousand needles allowing for a port and exploration of the drowned zone.)
Lordaeron(Menethil harbor and up, Menethil harbor has become a HUGE transportation city after Danath troll bane reclaims stormgarde keep, the horde Fortify Hammerfall and make southshore a large horde port that rivals Menethil harbor. Gilneas is reclaimed and the wall is repaired, and more things, possibly silvermoon relevance, Quel’thalas update)
3. Boats - 3 things out of this. Each faction has a naval capital. that capital is the new class hall (faction hall tho). You are able to send missions and boats off to missions;
1. you get to have a few types of procedural generated boat content, be that a sea battles, cave exploration, or faction stronghold infiltration. so there are PVE elements and PVP ones but both are "soft" pvp/pve content that can be solo'd OR grouped with up to 3 players with. look up "underground expansion The Division"
2. You have a main travel boat to get you to the different islands / ports of the world. players boats show up in docks.
3. Boats on the open water ( you can take the boat in and out of the harbor (this is how you go to start your missions, you leave port, head the direction of the mission, and then phase out into the "scenario") you can also tour around the continents. for quick travel, go to a port and fast travel like the vindicaar, for more varied, but more dangerous travel, take your ship to sea where you can be met by kraken creatures, pirates, but you may also find islands, , caves, and other treasures [technically speaking these can be seperate zones for exploration only, at max level, that have world quests attached to them] This also plays into making the faction hall look alive, you can see other players leaving / entering in their boats. Same goes for the port cities.
Mid-tier features:
See boats #3 it ties into the major boats theme but acts as more of a mid tier thing, the world quests specifically.
New customization (tattoos, scars, new hair styles, light implementation of subraces[models already in game such as broken, taunka, , with promise for more to come]
World quests for the whole world, go defend westfall and other places that are more rarely seen these days. (scale , lvl 18 sees level 18 enemies so on so forth)
Minor features:
Player Houses in Major Cities (multiple locations in every city, choose where you want to lay your head, ability to set hearth here. The actual “house” would be phased to players and their groups, but when looking out a window you see your live server) (unlocked through quests at end level, purchased with gold after the quest chain is complete.) (multiple locations as in tier options, for example t1 house in SW would be in the trade district / old town / dwarven district. T2 would be overlooking the SW docks, t3 would be a room in the mage tower. The same goes for each city. You can have all 3 teirs if you have the gold for it, and you can unlock the house in every city.)
PVP 1 v 1 duels, either que or group up with a friend to duel in an arena with pvp abilities available.
Permanent brawls, variations on BG’s with weather systems.
