tpvp ?
Not really sure what you are trying to ask but…
I don’t like using the word viable, instead, I use good/bad.
For example a 3/3/3/3/2 build (just random) will probably be not as good as a standard 6/2/0/0/6 power necro.
So no, not every build is ‘viable’.
you can go earthier power/condi. I prefer condi, but you can make use of both of them. It’d help to ask what kind of build you are looking for, because there are a few(power, condi, MM)
