This is not meant to be mockery or insult but is this your first RPG you playing? I'm not a gamer but that much I know to summon extra caution when it comes about locked area just as well as I know that a locked chest hides good stuff. At level 5-8 you should do exploration and outdoor quests. All the gates have the difficulty similar to dungeons in D&D games. Enemy level is the not same as difficulty. Example: in story mode you can defeat that champion at level 10-14 providing that you can manage the team working to maximize the damage (exploit stats effects and detonations). Other than that, it's always an option to come back later for that quest. Another point of view, a great fight is rewarded with great items which at low level might not be so great. In this game, assessing the difficulty is part of game play. It's your job to choose which companions to assist, what skills to use and how to fight. That of course when you can choose the fight. Main story is somewhat forgiving in terms of difficulty.
That's how it looks when you get great items too early:
When you are talking about the items and getting them "too early" doesn't make any sense to me. One is a unique, one is a typical item. They have nothing to do with one another.
