I did a good search or two and noticed similar threads about the lower lvl arenas, but not quite what *I* personally had in mind. If I missed any, my apologies.
While I realise it's unfair to have top armour in lower level arenas and this does not give any of the newer players a good chance to at least have fun, what bothers me is the fact you can stack teams. You don't even have to be a new player to get owned, you could be someone whos poor and can't afford the armour, etc. and wouldn't have much fun there.
The arenas are supposed to be random, right?

The next point I want to make is Factions characters. We all know that prophecies chars have to wait til desert to get +30 Attribute points through quests. None of the lvl 1-15 Prophecies characters will have 30 extra points in that arena unless they had $$ out the butt to get run. A Factions char can easily get run, grab kaineg armour, and before they even leave the first island, they can easily get +30 attribute points and make the 1-15 arenas even more unbalanced. Maybe factions chars shouldn't be allowed in the yak's bend arena.
I love GW and I play with my co-workers almost daily when business runs slow, and hope the game gets adjusted so the arenas are fair AND fun to play at least in the future.
