You are an optimistic person are you not :p ?
Breathing bubble/Mass breathing bubble ==> Do you really have issues again clouds ?
Erratic wisp ==> Do you like being teleported right in a pack of enemies ?
Turn to oil, bleed fire, dimensional bolt, planar gateway, ... the list is so long I don't even want to list them all again. Have a look at the survey, a lot of people highly disagree with you.
Well I was kinda irronic. Every skill does something, that's a fact. What they do however, is often useless or very poor compared to others.
If you answer the survey you will be able to see the rating for each skill. You will find that Uncanny evasion is in fact a good skill. Being outshined by other skills does not make a good skill a bad one.
Sure it's not. However, if I need to choose between them, why would I go for uncanny ? Similar abilities should be better in some scenario, not in all scenarios.
This is not about theorycrafting but more about liberties of character creation. One of the strongest point of DOS is being able to create your character as you feel. But with many useless skills, a lot of hybrid class cannot come to life. If those skills would become relevant, it would change a lot of things.
I'm in the same boat here. I'm not sure the correct therm was "theorycraft", but my point is that some rebalance is needed to make every skill a desirable choice for a specific build or situation.
