I last played when my old guild killed Heroic Nefarion in Cata top 25. I got bored silly of raiding/pvp since I had played in top 20 guilds since Vanilla and was Glad in arena multiple times. I am thinking of resubbing mainly due to boredom of other games out and school will be starting back up soon.
1. Is it worth coming back and playing catch-up. How long would it take to be raiding/pvping at the top tier again?
2. What class? I played rogue 90% of my time and druid a majority of the rest. Still good classes or should I level up a monk and give it a shot?
Just looking for opinions as to whether this is worth my time or I should just wait for the next xpac and/or ESO.
