I'm happy to hear other suggestions of how to fix Confront. But there are real limitations. There is no indication that Scrappers as a whole need either Offensive or Defensive buffs. Certain sets could use help, sure, but that's not what this is about.
Any suggestion of how to fix Confront must:
A) not improve Scrapper Defensive or Offensive performance directly
B) retain the basic concept of singling out an enemy (but need not necessarily remain a Pull ability)
C) make the power generally attractive to take for every Scrapper, but not so important that it becomes must have
Leaving it as is is NOT an option, as right now Scrappers essentially only get 8 powers in their primary.
