ENY works to make things fair. Nothing in the MA can actually force things to be fair... as in one on one. ENY works for the whole team. Now if that whole team decides to be in one place, it is going to be tough on the other side. That is unless that side can muster it's team to answer. We see that work and fail all the time, they answer the call or they don't and the base is saved or lost. Just as in war but with no real lives lost.
If everything in the game were fair in the MA, it would be the most boring game around.
Other arenas have been added for those with differing wants and needs but the folks asking for them do not fly there. That is why it is said that folks have no idea what they really want.
I agree on the MA assessment but would like to add an obvious observation on the additional arenas.
The event arenas are a necessity for events to exist and although the participation in events has dropped a bit, there is still enough interest to warrant such.
The AvA arena would see more participation with more organization among the player population (especially those that participate in events). Without such, players may decide not to enter the arena when it reads '0' currently in it. Those of us that do enter, hoping another may (or more) will only stay until a couple of sorties, that approximate a small tour of the map, then we move on to where there is some action. It's disappointing but I think promotion of the AvA to players currently in the MA would help. It did, somewhat, in the past. But it needs to be promoted honestly and perhaps tweaked, accordingly (many a new player being disgruntled with no icons and such).
The WWI arena is the only environment to enjoy WWI planes. It is much in the same boat as the AvA and players have enjoyed it as long as they organize enough to be able to enter it when they know others are coming in to play.
I think the existence of 24/7 event style/immersive arenas with unlimited lives but traditional foe plane sets are the cat's meow and I've decided to promote the AvA again with gusto. I'm considering doing the same for the WWI arena.
