They could fix Stronghold instead. Make it so instead of babysitting NPC's we can actually break the dumb doors ourselves with explosives. Spawning archers is basically useless when you can kill the dumb mobs in a few hits; and the skritt bombers die if you sneeze at them. Defending them is impossible. Summoning champions is actually kinda nice but also a waste of time.
So instead, make it so when you spawn, you can immediately summon your champions (All of you) and then defend them while yall march through, or play offensively and go to the enemy. Hell, anything but what we have would work better.
Capture the flag would be nice, too and then maybe put it all on rotation so 1 week we get ranked Capture the flag/Stronghold/Conquest.
But again, before that can happen, they need to seriously look into Stronghold and extensively test Capture the flag.
