You can play via free trial up to level 35 at no cost other than your time. If you want to get a better idea of what all different armors can look like, you're better off running around in the towns in game and seeing lots more people, because not everyone posts screenshots of their glamours online.
If you are that fed up with WoW, then you shouldn't need anyone's encouragement to play...well, anything else, really. Take it from the likes of me, with 20k+ achieves, right at 300 mounts, 80ish exalted reps, etc. (I assume the link in my sig for my WoW profile/armory still works). I had all sorts of shit in WoW. Left it behind and haven't missed any of it. There's plenty of such things to find in this game. If another game came along and I found myself having more fun with it than I do this game, guess what? I let my inner circle in game know I'm gonna go play something else...and there's a fair chance some may join me.
