Guild Wars 2

WvW=large scale pvp 100+ players
sPvP=small scale pvp 10-20 players
World=large scale pve 100+ players
Dungeons=small scale pve 5 players

Where is the medium scale pvp and pve? 30-100 players with map-size to scale.

Where is the commander-squad size (50 players) party gamemodes?

Where is there a way to assemble a squad and then assemble parties within that squad from there?

Just more gaming option suggestions…or questions.

You can be in a party and a squad at the same time.
Commanders cannot be in each other’s squads but can be in the same party. When a commander is in your party, you see a blue party dot in the middle of his commander tag.(If you’re in another squad, you probably would only see his blue party dot. – not tested)
You can see squad way points from your commander, and party way points form your party. The same with map pings.

well commanders would be able to assemble these teams himself/herself.

for WvW get rid of the PvE message stuff on the top right side and put more wvw types of things like commander messages or quick alert icon messages from players.

for WvW have another mini-map on the bottom left corner that has overall view of the whole map and dots of squad members and members of the whole team on all the time. command info could be pinged there to show where to go and any other command information.
