1. He was very competitive in 5th when you turned up to a game with alot of tanks, and to be perfectly honest, he is still very competitive now
2.
Pros:
-Re-roll to hit Melta/Flamer/Thunderhammer
-Cool colour scheme (
imo)
Cons:
-Short ranged (melta typically being 24" or less in range)
-The cost of vulkan means you have to ensure every unit takes advantage of his ability when making lists at or below 1500 points.
-The loss of combat tactics means you cant choose to fall back. Meaning alot of wasted turns in combat.
3.
-Dreadnoughts. Multi-Melta is basic wargear, can upgrade to include a flamer. Iron Clad is best (i think?), especially in a drop pod.

TH+
SS Terminators (with their Land Raider to ride in)
-Combi-Melta sternguard in a drop pod. effective suicide tank hunters
-Land Speeders w/
MM. Likely to be glanced to death, but 60 points a pop is not too much of an investment.
-Attack bikes with
MM - Bikes have nice rules (relentless/jink etc.) combined with a re-roll makes them pretty good.
4.
Vulkan, well, it wouldn't be a 'vulkan' army without him...
Tactical Squads (around 2 in a 1500 point list).
IIRC, they dont come with bits for a
MM, so you'll have to get that seperately.
Rhinos/drop pods (which ever route you wish to go down)
The rest depends on where you want to go with it,
tbh
