Help for an old lady....

Ok, so... as I age, I notice that my response times and finger dexterity is beginning to show signs of slowing down. As a result, I am in need of some suggestions for a build that has some survivability and can still hold its own enough to be at least somewhat competitive in a group PvP situation or support for my hauler friends without having to grow another set of hands.

Right now, I have two builds that I run with, but they're both keyboard intensive and depend on extreme mobility. One is plate melee and the other is cloth caster, so either way, I should be able to use my existong armor with a few modifications...

Help?
