Great guide. I would like to point out though to anyone who hasn't figured it out that if you are fighting 1 minion/lieut that if you hit them with any slow attack (even Mental Blast) their refresh time (for most villians) becomes greater than the time to cast Psionic Lance. This means wait for them to swing (miss or hit) and immediately fire PL. You won't ever get interrupted this way and at low levels nothing can compare to the damage of PL.
Also on this note.
If you take Air Superiority it does about the same damage as Mental Blast but has a faster, cast, recast and gets a knockdown EVERY time. The time it takes a villian to stand up is more than enough time to get off a sniper shot with PL. AS refreshes quickly enough that you can often keep one mob down almost all the time so that they don't get to attack much. It takes mob about the same time to stand as it does to cast Mental Blast so in very early levels you can use a 2 attack combo AS, MB, AS... without any down time waiting for a refresh. At early levels where you don't have a lot of attack powers this can get you out of the Brawl basement.
This is also why Mental Blast isn't worth it. Getting a knockdown every time and a much faster attack makes the pool power much better IMO. For anyone who hasn't fought using knockdown you have to try it. As long as you keep hitting them they just bounce up and down without getting to fight back, it is very powerful.
