Rank I UR (and Rare!) builds

(EDIT: Feel free to add rank I rare character builds as well.  Plenty of people want to make the most of their low-level rare character kits too )

It's pretty easy to find recommended rank X builds online for UR characters. However I'm sure there are plenty of people out there like me who are unlikely to get their UR characters beyond the first few ranks, so I thought it might be helpful if people who have experience with particular UR characters post their suggested rank 1 builds - i.e. using a maximum of 59 of the possible 82 skill points (the missing 23 points being acquired through extra cards).

The only UR character I actually have is the Angara Exemplar so I'll start with my gold build for him:

Overload
4b - recharge speed

Barricade
1 (just a 1pt panic/herding/objectives button)

Energy drain
4b - recharge speed
5a - extended drain/priming

Bioelectric focus
4b - efficiency
5b - focused damage

Bioelectric defense
4b - regeneration
5b - augmentation
6a - bioelectric ward (feel free to move this to rank 6 of ED or BF if you prefer, I just find the extra DR more forgiving)

Weapon and equipment
Hurricane or Rozerad with barrel and magazine mods
Incendiary ammo + your choice for second booster
Expert package (that's what she said) or pistol amp (that's also what she said...?)

Playstyle
With chain detonation (rank 3 of BF passive, primes enemies in the vicinity of the Exemplar's tech combo detonations) and insane recharge speeds, this guy excels at setting off combos all day long. He also has great survivability with ED, barricade and the BD passive.

Use ED as a detonator where you can, as this will still let you take advantage of the shield restore over time effect. Just remember not to detonate debuffing/DoT effects that your teammates have cast on bosses.

I love the hurricane on him (and anyone else) but use whatever you like, provided that you don't gimp his glorious power recharge speed. I recommend using equipment that boosts your preferred weapon's damage because he doesn't have much in the way of native weapon DPS.

Incendiary ammo helps with armoured enemies and sets up fire explosions, although disruptor ammo will synergise well with chain detonation if you prefer. The 360 degree melee is handy to finish off dogs too.
