I leveled a DS Mastermind and took the whip attacks early. I got the most use out of the AoE attack and Corruption for its fast recharge, and used these skill often from level 10 onwards. Once you have all three and are high level, you can chain them together to stack a good amount of -Resistance and significantly enhance your pet's damage. I found this style of play to be the most interesting on MMs-- taking your attacks early and using them often.
Remember to keep at least 2 of your pets in Body Guard mode (defensive/follow), if not all of them when fighting up close. You need the extra HP this effectively provides. I would also highly recommend getting a -knock back global IO, either a low level Blessing of the Zeyphr or one from the defense/resistance sets.
DS will work fine for farming. Thugs and Robotics are probably the best at this, but I would recommend taking a character that you find interesting, and Demons are very good at both damage and survivability.
As for secondaries, DS/Thermal can be very good with just Single Origin enhancers; it has heals, buffs, debuffs, and looks great with the Demon theme.
I have been quite happy with ds/dark and bots/traps. Bots/traps, at level 37ish, is pretty much habitually running at x8.
I have a Demon/traps MM, after a few procs, pet auras and sets slotted she can pretty much do it all. I've soloed AVs and GMs with her, and also regularly run her on +0x8 shard & drops runs
If you're the farming type (I'm not, myself) then you'll be wanting to get the */Traps or */FF secondary. This is because these are the two simplest sets to softcap your survivability on and hence take on 8-man spawns solo.
Many will recommend */Traps as the more all-rounder since it has debuffs as well (didn't like Traps, personally, in CoV Beta as I wanted something that could manoeuvre better - this was pre-Inventions, so no consideration of "softcapping")
You could also look at the Thugs primary which allows henches to be easily softcapped, as the Gang War power takes Recharge Intensive Pet Sets (so you can slot for addition +Def and +Res auras for pets).
Demons/Traps or Demons/FF would be popular choices for farming. Others could likely do as well (*/Dark is popular for the amount of -ToHit which acts, functionally, like +Def)
right now i desided to roll with a bot/traps but i dunno its handleing oddly, demons whip attacks are nice but the demons are ugly and that bugs me, so between bots and thugs what one is the best for farming lategame? like i said befor this character is mainly going to be used for farming so i can give in to my altitis later.
and btw thanks everyone for the help so far.
Unfortunatly, looks are that and that alone and something you may just have to live with. As for comparison between thugs and bots, Bots will last much longer thanks to the protector bots so they're probably your ideal choice. Thugs on the other hand tend to be a little more squishy and require a little more attention, but the extra risk is rewarded for the much higher damage they produce, particularly in the AoE depeartment.
Since your new i would recommend bots.
ok im new to the game and mastermind has caught my attattion buuut i dunno what is the best primary to go with? i like DS cause of the whip attacks( i like being up there with my cannon fodder) but i dunno is this something that would be better for me lategame? i intend to use the MM to farm so that i can support any other characters i make.
anyways off to work ill be back in 9 hours to check this thanks ahead of time for any advise.
