I came to a realization recently. Everyone I've ever played arena with dislikes these two maps. I played a lot on the Tournament Realm when it was up, and random skirm queues always had people complaining about them.
In my opinion, they were plagued with bugs and design problems from the start. Boxes that caused LOS problems even when they clearly would not. Rando fire that would kill you without warning. Warlocks camping out in the pipe. The way people could nose their way into your starting area and fear you prior to the beginning of the match... Yet despite all this, they were kept active in rated play (for a long time).
So they fixed a lot of that, and I found that once I got past the wild and crazy bugs and randomness...I, and many others, still hate these arenas.
Ring of Valor. Starting this close to your opponent was a novel idea that I feel has largely worn on us. Sometimes it seems DKs can catapult their horses to far into your side and drop a DND so quickly and far away that there is nowhere for a rogue to hide, even if he runs straight back. (and god help you if you run forward, you're just asking to get holy novad, arcane exploded, DND'd, flared, warrior shouted, etc etc etc) Starting in close proximity is not that bad of a thing, except for stealth classes. But I'll just leave it at that.
Let's say you're trying to recover from a warlock or a mage trying to burn you down, and you seek refuge behind a pillar. Happens all the time in arena, right? Well it just makes me sad to lose a game because at that moment, the pillar decided to disappear. Or conversely, a pillar arises, blocking the LOS of a crucial heal. Yeah, these things are on timers. Doesn't mean I enjoy the gameplay of this arena. I prefer static surroundings, within which you have a dynamic competition. (same reason I turn items off when I play super smash brothers. :P )
And then there's Dalaran, same problem with the water spout. Just don't like it. Would be a pretty okay arena without it, I'd say.
As far as I can tell, someone had the ideas for the arenas and just would not let them go. It's as if they couldn't accept that arena's don't have to be flashy or unique or special. It's the players that are the stars, they will make a good, fun fight without environmental hazards. I'd much rather see a fight end when "that RMP team pulled off a great CC chain on the healer while focusing down the rogue" instead of "the pillar dropped down when the shaman was trying to pole hump, so then the warlock two-shot him."
I just wanted to take a poll and see if I'm alone in my dislike, or if it's true that most people really just don't enjoy playing here. For archive purposes, my preferred order is... Lordaeron, Nagrand, Blade's Edge, Dalaran, Org.
