Hey there druid community. I was pondering the idea if leveling only be doing dungeons from lvl 13 to lvl 60. 
The idea is as follows: 
- level normally till you reach lvl 13; 
- head to Orgrimmar and camp the Ragefire Chasm and spam the channel for groups; 
- get to 17 and head out to Wailing Caverns in Barrens; 
- get to 22 and head to SFK in Silverpine 
. 
. 
.

. 
. 
. 
- reach lvl 60 by doing Strat and Scholo. 
  
How viable would a strat like this really be considering you will always have the desired items dropped from the respective dungeons plus you'll get to really exercise your role as a tank/dps/healer.  (downtimes for learning skills and resupplying with consumables was not taken into account).
