CE gear espcially can all be randomly given to you on normal. Little to no skills needed. Just decent weapons and lvl 30 players. VoG you have to play hard to get a helm. Skill required and a good team of not made up of idiots. IB gear, you actually have to level rep up then purchase with glimmer, takes more skill and is more frustrating. Can be filled with idiots too. Takes more time to acquire required rep and glimmer.
