As previously mentioned, Illusion controllers can take deceive Sky Raider FF Generators to put bubbles around their teammates.
When an illusion controller deceives Avalanche Shamans, the earthquakes they cause will hit not only your enemies around them, but the Shamans themselves. Ditto for Storm Shamans and their storm clouds. It's fun to watch.
Mission critical objects (TV reactor core, time capsule, war wall generators) can usually be bubbled.
Want to drag a whole bunch of your enemies to you? If you have a power like Darkest Night, target the enemy farthest from you, hit them with it, and hide. They'll run toward where you're hiding and aggro everyone else as the run by. (It's a good idea to have something like a tank on your team standing between that group and your hiding place.)
You can exemp into a TF, but not SK into one.
And for anyone who's really just starting out, you can open your chat prompt just by hitting return. You don't have to click on it every time. (Related: The backspace shortcut for tells was mentioned earlier in this thread.)
If you are a tank and something calls you away from the game in the middle of combat (i.e. phone, pet barfing on the carpet), you can still hold aggro by targeting a team mate, setting taunt on autofire, and hitting 'F' (default for follow). Anything that teammate targets will be taunted by you. (The defenders I run with also find enormous humor potential in this technique.) Just be careful to target a team mate smart enough not to point you toward a set of +5s. . .
As stated in their info, when a Banished Spirit of Death sees a hero, it can not be distracted from that hero. The only way to pull it off is to defeat it. (Don't actually know, but maybe deceive would work, too.)
You can run on top of the trees in the middle of Perez.
