It's one of the issue of this game and the heavy handed scaling system, which is said to be getting worse during the mid- and endgame.
For the spear you should not need Teleport-gloves, just enough strength.
In my opinion, the way how they start the story is the core issue of the difficulty level. You start with nothing while facing of kind of the elite team of the Magisters. There fore those Elites have to be weaker than the logic would demand and still they are harder than the stage of the game progress should offer.
