Hi all. This is my first post on dakka dakka - I came across it while looking for 5th ed rules rumours (Yeh, I know that's been done to death

)
Anyway, I've been thinking of starting a new
SM army for the next
GT season and wanted to get some second opinions. Not sure obviously how bad 5th ed will nerf any of the stuff in here, so I'll probably hold off until later before parting with cash. Anyway, here goes.
Master, Powerfist, Combi-melta, Frag/Krak, Term. Honours, Iron Halo
Dreadnought, Assault Cannon, Heavy Flamer, Extra Armour
10x Tactical, Heavy Bolter, Flamer, Vet Sgt with Power Weapon
10x Tactical, Plasmagun, Plasma Cannon
5x Scouts, Sniper Rifles
3x Land Speeder Tornadoes, Assault Cannon and Heavy Bolter
Land Speeder, Multimelta
Land Speeder, Multimelta
Predator Destructor, Autocannon, sponson Heavy Bolters, pintle Storm Bolter, Extra Armour, Smoke Launchers
Whirlwind, Smoke Launchers
5x
Dev Squad, 2x Lascannon, 2x Missile Launchers
1495 pts.
Not perfect, obviously - needs a bit of playtesting and running in, but all hints would be appreciated.
Cheers all
