How to actually get to the end of a tree?
I've been working on my French tree for over a year now, and my problem is that whenever skills higher up the tree start to degrade, I feel like I have to go back and do them before moving on. For me it's a perfectionist thing, I have to make the entire tree gold before doing a new lesson. Does anyone else do this or do you just continue with new lessons even though your previous lessons have degraded? Do you go back and refresh them or do you not worry about it until you've completed the tree?
I don't worry about them unless they are degraded by more than one bar. I completely understand the perfectionist thing and I myself like seeing my tree all golden but until you can accept the fact that it is really hard to keep the entire thing golden, you will have a hard time ranking up. Another strategy is for you to finish the tree without worrying about the others and go back and strengthen all the rest of the skills quickly in one sitting. That way, they don't have the time to degrade. I hope this helps!
I tend to keep the skills golden as I move down a tree, especially for the first two thirds or so. I use the "Course Progress" and "Updated Tree Trimmer" userscripts to help manage my progress downward better.
Past the halfway point of the tree, it is often more time effective to let skills lose two or three bars before refreshing them. Once you have become used to using the Tree Trimmer, it should be easier to keep track of which skills have decayed most and concentrate on them.
