I am very, very confused about what the intent was with the changes to virtue scaling on the starting pacts. The effects of spirit and grace are weaker across the board. All three pacts now scale best with courage, and all three can be built in almost exactly the same way, with the exception of Oscelda not really needing sympathy. I sincerely hope this is a bug.
I have not yet gotten through testing the other pacts, so I cannot yet offer an opinion on how virtues affect them, but when it comes to the three starting pacts, weapon attunement is the only reason to have points in anything other than courage. Base values for duration and range are adequate for almost any situation, and the value gained through adding more spirit or grace simply do not compare to the value gained through adding more courage.
I really like the concept of strength, duration, and range for courage, spirit, and grace. We know from Warframe that these three attributes can work well for ability scaling, but we need that scaling to actually matter in gameplay. If I need to compare two clips side by side to be able to see the difference between range at minimum virtue versus range at maximum virtue on a max rank envoy, then something is not right.
I really hope this is a bug, that somewhere a decimal is out of place, and a hotfix adjusts it soon. This system has a ton of potential. Please don't make me bless my starling with courage. [edited for typos]
