Electric/Shield is a burst damage farming character. Shield Charge and Lightning Rod are your main AoEs, and the best you can expect to get their cooldowns is just under 30 seconds. This means they are best suited for moving into a spawn, AoEing everything to death in a few seconds, then moving to the next spawn while their AoEs recharge. They can function as a character that sits in a spawn and continuously AoEs, but are limited in speed because of the recharge times.
Some other farming characters to consider are anything with Fire (armor or melee) and Super Strength. Look in the Brute forums for the "Very Best Farmer?" thread to get some ideas on what can farm well. A Fire/Kinetics controller might work well for you because it doesn't require an expensive build to get started.
The Mode button in Mids' allows you to set it to PvP (player versus player) mode. The rules for PvP slotting are different, and some powers may work differently in PvP. I know very little about PvP.
I have two builds that i'll show you, wondering which one I should go with for farming?
Other questions (may need to be answered first).
Is Elec/Shield good for farming AE (mostly ambush farms)?
If not, which is? Fire/Fire tanker?
In Mids what is the point of the "Mode:" button up the top? What does PvP Mode do that PvE doesn't? etc.
If you're on a computer that you do not have Mids on i can export a longer version of the build, but for now it'll just be the data chunks.
Hope you can help, thanks in advance. = )
EDIT: One does have legacy fitness and i hadn't realized. Something can be done about that I'm sure.
