Hi all, I am enjoying the playstyle of masterminds, and i have started a few different flavours of them. What I would like to know is what combinations of primaries and secondaries are the best for most content including AV's and GM's? I mainly play solo with just a little bit of teaming. Currently I have Necro/Dark, Bots/Electric, Bots/Traps, Mercs/Marine, Demons/Electric. Is one of these better than the others or is another combination preferred? Or am I looking at the wrong AT all together? I like the fact that masterminds combine damage, tanking (for self at least, through bodyguard mode) and support through the secondary. Any help greatly appreciated.

Hello all, I have been enjoying my bots/FF mastermind, i love how survivable it is. I am level 29 and the bots have defenses at 47% and my personal defense is 30%, just with common IOs. I have some questions though: 1. What APP/PPP would you choose? I am leaning towards Mace or Mu for the aoe immob. I know that the Mu immob. is better because it protects against knockback, but Mace has a defense armor that would stack with the bubbles. 2. Mace also has power boost, what does that effect on a bots/FF MM? If is affects the bubbles do you have to "re-cast" them after activating power boost? 3. I have never used sets before, alt-itis affects me before I get past level 30. But what budget sets should I be saving towards? My plan is to keep using common IOs and buying cheap sets where I can, then once I have achieved 50th level start earning towards a purple sets. 4. Is bots/FF a good combination at higher levels, I am mainly soloing and the MM archetype seems to be the most survivable and faster killing err arresting character. 5. Are there any power pools I should look at? Currently I have maneuvers, assault and tactics from the leadership pool, as well as fly (my preferred travel power). Thanks in advance.
