if anyone is still interested although kind of old news imo, by doing both Turan solo dungeons Isle of Iron Statues HM and Dead Man Island Unchained, nets slightly above 300K AA xp and 6-8 rare tokens. It all takes 30 minutes of time if done properly. These does not requires premium also, as long you paid for the expansion.

In Iron statues, all you have to do is to trigger HM, kill the spider and the last boss King Kong . The NPC outside instance near boat, will also give a quest to slay few animals which net 17K AA xp, so take it.

In Dead Man, you need to take quest from NPC near boat and kill just three bosses in sequence according to the quest, and do the random final boss, this one might be tricky as one boss is a dps race so is gear dependent.

All instances can be rushed skipping many mobs to get straight to the bosses. In Iron Statues, you can die only after you trigger the HM, before not. In Dead Man Unchained you can die as long as u want you still get the same rewards.

You can do all above once a day based on the cool down.
