Hello and thanks for reading my post. My guild is planning on merging our 2-10man groups and forming a solid 25man raid group from now on. The problem is I have not stepped foot into a 25man raid since wrath hence I have questions about which bosses require 3 tanks vs. 2 etc. I have watched all the tankspot videos etc but would like to know if you can point out the major differences if any between the two sizes. My guild is currently 11/12 and should have 12/12 this week hopefully. Thanks for the help.
(please list changes if any to these bosses or put none- i.e. on 10man it requires 2 tanks and on 25man it also requires 2 tanks for example)forgive my spelling on some of the bosses names.
