That was indeed a very usefull addition, (may be inspired from DotA 2 which has a similar system).

What I would like to know, is where will all those builds be saved. If saved on the users' PC's, they may allow hacks, while if stored in the servers, wouldn't that be too much Data to be stored, without side-effects?

I have to find out.
