Playing around with the last pieces of fun content WoW offers, I found that playing low-level Warsong can actually be really good. And I am not the only one. Waiting times are better than at max-level!
Of course, the lower levels are dominated by heirloom players, so you need to pick your class and specc very carefully. Playing a warrior, paladin, shaman, warlock or mage without being heirloomed and enchanted is pointless. But if you can stealth or kite and find a nice weapon on the AH, hunters, rogues or druids are really good.
I recorded one of the more fortunate matches. It's 13 minutes long.
I think it is very interesting how low-level Warsongs are functioning. The amount of abilities the characters have is minimal, but that makes the entire game very tactical, especially for a not-heirloomed rogue. And even though the game is so dramatically unfair (I can't win a fight against a heirloomed char with 500+ hit points, nor does anybody with less than 400 life have a chance against my stealth attack), and even though I can die within the fraction of a second to even not-heirloomed characters, the game is pure fun. I played like 20 matches in a row yesterday; and not every one went as well as this ;)
I absolutely love the pace of this game without mounts. It's not the use-every-GCD-style of the endgame, but, well, much better: you can concentrate on what is going on instead of on your actions bars. Oh, and no magic explosions are plastering my screen, no absurd amount of AoE effects! And great looking character models!
Of course, this is not playing a MMORPG. It's more similar to any matchmaking PvP game and it might be hard to justify paying a monthly sub for this.
In the name of gameplay that stealth animation is now unpolished.
