Which is "better" in leadership?

Tactics generally, but I also generally slot it up a bit and put a gaussian buildup proc in it so I still get a bit of the dam boosting that assault would have given me anyway along with all the benefits of tactics.

Unslotted? I'd still probably go with tactics for the perception unless I was on a defender with ample ability to hit pretty much anything out there (ie strong -def like sleet) then I'd go assault because defs have such high value on it, and did on my storm/sonic.

Would a team with a bunch of people running Tactics drive Controller and Dominator pets to suicide?
