Again, after playing controllers, doms, and everything else heavily , and after being one of the biggest farmers on Freedom server when it was live
( my brute was arguably the fastest farmer in the game tested by extensive competition)
If you want to farm, and you want a controller, the best way to go is fire/kin with plant/kin being very close or just as equal depending on what map you are doing .
Far second is fire/rad ( I did farm with fire/rad too but it's never near enough a fire/kin).
But if you really want to speed your farming and you want a controller type, and you want all map types , then , sorry, but the Dominator is where you want to go
Fire/Kin is truly a king but only in open mops with mobs extensively spread out.
A Dominator has much greater control than a controller , so he can deal with maps with not so much safety as a controller requires to survive
That is the only reason Dominators can be so reliable for farming with great speeds, because of domination
Fire/Kin tops on open maps, but dominators on almost any map can do it very well
I had farming speed competitions over and over on Freedom
My plant/thorns fully decked out with IOs was far faster than a fire/kin when an assortment of maps were used, but the standard map on P Island to farm with fire/kin was always looking like it was made for fire/kin and it was too good.
When mission architect came out , the BRUTE emerged as the ONE
SS/FIRE brutes outclassed any and all other farmers in the game when mission architect came out
Concerning plant for farming --
Now, I know confusion diminishes some XP but, BIT BUT... the speed of your kills makes up, MORE THAN MAKES up for that.
Since you are clearing the maps faster and resetting faster, the fire/kin is getting behind even if he has no xp/kill penalties due to enemies being confused
Nothing damages those minions faster than seeing their own bosses owning those minions , you are just there to provide support and additional damage to ensure the quick end.
Now plant is a damage monster in it's own right, position your thorns damg angles just right and you will clear the group in no time.
OMG
I am so glad I found this forum today .
