Assist and Guard

When someone purchases a skill they have invested time and money on what was advertised. Would you buy a car if at any time the navigation could be turned off? Or the wheels downgraded? Think about the skills "before" you sell them and leave them alone after OR give full refunds if you decide to downgrade them. I was about to invest in the skill Guard and realized that it was the same as the original assist. I'm too nervous that it will be relegated to a trigger skill too so I decided not to. Downgrading assist and leaving Guard leaves an imbalance for those playing against a strong front line. It doesn't seem fair given the advantage Earth already has over the other elements. Please put Assist back the way it was or downgrade Guard if you are working to keep the game balanced. And really take a look at the balance of the characters and leave the skills alone.
