If you need a simpler, easier style of gameplay to better improve your performance, you can have it. Your performance won't be optimal, most likely, but you'll still get pretty close.
Right now EB and PE are close enough that it's a "pick whichever you like" point, for Elemental at least, but UF isn't that much further behind, particularly with the recent hotfix to Lightning Bolt (which I don't think is enough to change which talent is on top; it just narrows the gap).
Another player who IS concerned about min/maxing their personal DPS to a greater extent, or who is a bit bored by the basic rotation, could pick EB and be happy as well.
Same kind of rationales apply to the Tier 4 talents as well, FWIW.
