Build request for Mech repeater.

[Jaysun]

So right now I am an 18/2 Rogue arti mech repeater. I have all the past lives that really make this shine (doubleshot, enchant weapon from epic, 3 ranger, 3 rogue, ect). I am currently working on racial TR's for the stats and more AP points because I play a bladeforge and the AP really helps toward getting weapon attachment/racial seeker while allowing me to maximize my other trees. I choose Arti for the rune arms mostly. The instant bolts are nice but with flame bolt scrolls not really needed.

With that said I am looking for the best DPS build with only a few guild lines. I don't know all the other classes well so I could be missing a build that would better do what I want it to and not know it. I know Pallies get the crit buff and many people use it but I have no experience with it, ect. Also with the arti pass I don't know what has changes that could make a mech build better. I would love a build where I was great at single target damage like all mech buils but also good at AE (Something outside of IPS).

My guide lines.

Bladeforge or a race that has great self healing. In heroic and EPIC (I don't like cocoon).
I prefer great crossbow because how many other perks it comes with and how well it works with Fury of the wild Destiny.
Can do all traps/chest in the game.
Epic Reflexes feat. I hate failing on saves. Even on a 1. Ruins the game for me...dunno why.
I have +7 tome with all content unlocked.
I am open to a bow build via ranger but still has the requirements listed above.

Hope to hear some good ideas. I am going to TR later tonight or tomorrow so looking to start messing with it.

Anyone on this? I know some of you have mastered the Mech Repeater build. It is a common build now but would love to know how you maximized DPS with yours!
