The one thing to be careful with regarding tank gear is that the "recommended gear" system doesn't work well for tanks until you get to Lv50 because tanks can equip things intended for other classes and the recommendation is based on Vitality (a stat added to other gear as well) instead of Defence, which is what you really need.

If using the recommender, check the stats of the suggested items before agreeing to equip them and make sure you're gaining rather than losing Defence.

If you're carrying but not actually using gear that gets incorrectly recommended, you can move it out of the armoury chest into your main inventory to get it out of the way.

Once you get to Lv50 (or Lv60 for jewellery) they fixed this issue so tanks can only equip gear specifically meant for them.
