when to turn into tank?

hi, im currantly a pure staker with lvl 50 range, im just wondering when i should start to begin to turn into a tank. i was thinking of just doing it now and getting 50 defence with 70 range, is that a good enough range lvl to be a tank? ohh...when i stake id stake with some parts of armour on (most likely sheild and pl8, or just pl8 and use the spec where ur def gets raised my 8 lvls) so, will this be a pwnage tank? ohh and id be staking 1mil every time just so that i can make a half decent profit....cuz pple will only stake me once then run lol

 

Don't train def
1 def owns

 

Tanks are quite good, but if you want a really good tank i would recommend 70 or 75 def.
Your range lvl doesnt need to be that high.. I would say 60+
