Subscribing to EQL+ does not unfairly improve your entry quality. However, if you experience payment issues, the Winsurance feature holds your order for 15 minutes after the launch, allowing you to secure the product with a new payment method.
EQL+ also allows a "second choice" option which gives you a second opportunity to be selected- for instance if you are okay getting a size 11 shoe vs. a 10 and one is available you can select that as a back up option.
