Been playing a bit team arena these days...
the arena there can go all the way to 30 minutes of pure battling... but we still get 10 faction and also that 30 minutes battling only have 6-8 death on each side.... In that sense, wouldn't you might as well just play random arena to get mroe faction? Because 30 minutes for 22-24 faction aren't worth it when you can just do random arena and get 18 in 3 minutes.
