What about Blackfire Torch? Every AP champ is rushing this item and literally snowballing. This items wasn't required, it just made strong characters overpowered. Why cant you disable this item from dominion?(since hextech sweeper is already present and similar AD version is disabled on this map AND DFG is getting buffed.. alot..).
On side note, with these new items there will be many cases of champion x getting overpowered with item y. So please keep an eye on this.
BFG is getting a significant nerf next patch. It's known to be overpowered, and that was done intentionally to fully realize the ramifications
