Crucible looks cool - but please GGG, plan for more convenience using the mechanic.

The requirement to have the weapon you want to crucify (put a skill tree on) equipped will make using the mechanic really inconvenient.

For example, I plan to play a trap build with a green gem, but it has spell scaling, so I will want to use scepters or wands. I will also want to level 6 copies of my green gem in weapon swap, to have a decent shot at getting one to level 21. I can't do that with weapons that I might use, unless I take the time and currency to chrome every scepter to 3G.

That means while hunting for a good tree I will have to put a new scepter in my inventory every map, epuip it for the league mechanic and unepuip it after. I am not looking forward to that. Even if I didn't have the socket colour problem, the league would still require regular cumbersome inventory management.

How about a crucible locker that you can fill with a handful of weapons, so you don't have to do additional inventory management every map?
Being able to crucify from the stash would work too.
