Removing Twists is going to massacre people that have completed the EDs, and earned the right to pick things for their build as currently available.
I know I use 5 different EDs in mine, as do alot of others. With the new system, not only don't we get access to them, we have to be 30 (+) by the
proposed changes to get the top tier we already unlocked, even in our main Destiny. We see where you're trying to go with this, but it's an Epic Fail.
But wait, there's MORE!
Adding BUILDERS, for skills that simply need a timer, or be passive?.... Seriously... stop. In no way EVER, does this game need another mechanic.
