52 might be a bit low for grouping in the planes and as far as the coolest zone, its yet to be seen. right now only the most uber guilds on each sever have the power to get flagged for most higher level zones i.e. the dragon quest in plane of valor. to even get to the planes to kill thes mobs you have to be pretty damn good to pass the trials. however, as everyone reaches 65 and gets all their higher level spells these kills will become easier. already guilds that were on the first and second tier are going after the "forgotten" temple of veeshan mobs. myself, ive grown far to impatient to chant kite and charm kiting is not viable because only like 3 mobs in the whole expansion can be charmed before call of the banshee. right now im justgrinding experience in plane of valor to get 64 so i can scribe my damn dreams of terris.
