I supply builds to most of the people I play with, because I really enjoy it. I'm by no means the best, but here are the basic rules I follow for my builds.
Get Mids' Reborn
Start by picking what you want to build for. Everything else will flow from this. For example:
Soft capped Smashing/Lethal defense
Perma Hasten
Capped resistance to X damage type
Try and get at least 2.0 end/sec net recovery. Net recovery is, with all the toggles you'd use in a fight on, recovery - endurance drain
Ideally this should be without click or incarnate powers active
Slot Miracle: +Recovery and Numina's Convalescence: +Regen/+Recovery in Health
Don't fear picking useless powers to unlock something good
Most notable example of this is Boxing/Kick to get Tough and Weave in the Fighting pool
Tough is a great place to drop the 2 +3% DEF(All) IOs from Steadfast Protection and Gladiator's Armor
Weave is a requirement for any AT that doesn't get an armor set to hit soft capped DEF.
