Hello i have a question i have on my char 3.7gs but cant go in heroics dungeos anyyone have a
solution for this problem ? It says You must obtain bether gear.

As it was pointed out by Mercy, you need certain ilvl gear across all gear slots. GS doesn't matter because it's a gear-measuring system created by players. Ilvl is what you need to look at.

In the past, I created this thread. You might find it useful.
