Gone has around 10 or so commanders, some NA, most are OCX and the styles and gameplay does vary a lot from commander.
The Game play for me generally depends on what we are fighting/doing in WvW. If we need to comp up we will. Sometimes OCX is quiet.. so you end up fighting gates and walls.. Sometimes gravity can be brutal too :D
But that could be said about any of the servers. In Late OCX, early SEA they do get more content/fights. But due to my time zone and hours, I cant really run too late these days.. We do have Shinto's HK group that runs later OCX as well on JQ. So theres always people to run with! and also Dent if you play early hours in the morning.
GONE is a casual guild, but we do have many now that are running set builds, in comms and are comped as a squad.
