Well, it’s not just close quarters combat, it’s a special blend.
I have two main characters in GW2, one is a human necromancer with a gaggle of minions around her to attack on her behalf. Specialist build that means her damage output isn’t what it could be, but the build is *ridiculously* survivable. Things that would outright kill other players (leaving them in need of resurrection) are often just swatted away because the build is about as mechanically abusive as it can be using what the game gave me to play with. This character has also been known to solo through various parts of the game designed for 5-10 players (albeit slowly) because survivable. Other parts of the game are designed for 30-50 players, but that character and 3-4 like her can handle that content between them.
Ahaha, there was one time, it was like a scene that needed Ride of the Valkyries as a soundtrack; 6 necromancers flew in, all landed and suddenly it was carnage, all 6 had without realising it, all brought minions. 6 necros each fielding 4-7 minions depending on build is suddenly a lot of players and helpers… necro squads don’t happen often but they are pretty heavily overpowered.
The other is a “charr”, a 10ft or so cat person whose personal motto is “if it bleeds, I can kill it”. Damage output is vastly superior but he’s squishier. Best when I’m not soloing things and just bring along the raw damage.
GW2 is pretty social and easy enough to get into.
