This I have to admit is one of the reasons I love this game. Fighting all the way to the Monsters bases and setting up turrets that farm XP/Gold for me is just a lot of fun. Right now I'm at the Stoneblade Mountain finally got the turrets set up around the trolls area and am farming the XP and Gold.

yes , turtling is brilliant :)
being able to leave the base fully defended and then build tons of towers around nmy camps :)
thats why i like the elves. cheap stuff and you can build them without limit :)
