Welcome to the game 
I have been playing for quite a while now, but have only limited experience with Rob/FF MMs. However, I can point you in the right direction. Of extreme use are the boards, both these and the american ones: US Boards
Go to the playerguides section, and then the guide to guides thread. (page 1 has a very detailed list)
Or to be more specific, here is the MM guide section.
For your forcefield powers, you might want to look at the Defender guide section. (these are archetypes in CityofHeroes, and they have had the ForceField powerset for much longer, therefore there are more guides available. Your powersets arent identical, but VERY similar)
As a final note, posts with questions like these should be made in the player questions forum
Good luck!

Wow, thanks for all the information
Been reading lots about it today, but too much info is just confusing, lol.
Welcome aboard!
You could also look here, Master_Zaprobo's Mastermind index with links to a bunch of guides and other useful stuff. Also, in the europe mastermind section there are a whole bunch of posts about robo/FF masterminds so take a peek at those too.
I wouldn't worry too much about the cold hard facts behind the powers; you tend to hear about the real duffers/uber powers so that should help with future power choices.

Hi guys,
) and have created a character on Union.
I've been looking at purchasing City of Villains since the day it was released and noticed the NCSoft stand at the Brighton Comic Expo last year where i could play a little of the game. I thought it was rather good then, and finally decided to take the plunge and buy it today.
I have just finished downloading what i hope are all the updates (Almost 2 Gig
I've played a lot of MMO's before and have never really found anything that's taken my fancy. Hopefully this one will be different.
Anyway, i have created a Robotics/Force Field Mastermind as it sounds rather cool. Any help that can be given will be greatly appreciated, and does anyone know where to go to get things like facts/figures about my powers as there seem to be none...
