Ok I have been playing a lot cuz of work and college but when I have manage to do dungeons and quest a lot when I can, today I did Heroic Nexus and I heard it is the easiest heroic.Thing is I have god def rat i think and good stamina but there were some close calls and 2 wipes I think it was mainly cuz we had no CC but not sure. I want to do heroic Utgarde Pinnacle and Heroic Culling of Stratholme for the shield and sword but I'm not sure if I am ready to tank it.
here is my armory just in case :

What should I aim for ? should I llok for regular drops? or just keep trying to heroic? and what are the easiests and hardest heroics?
Ohh also my total avoidance is 86% atm I don't know if that change now or if I still should aim for 104.2%?
Any help would really be appreciated

and ty in advance.
