it looks like a good list. lots of manouverability with some decent medium/short range firepower. Im a little worried that such a small unit of cc scouts wont survive for long and theres a lack of long range anti-armour support but I suppose thats surmountable with some clever use of that landspeeder mounted multi-melta and the tactical squads melta guns.
One change I would suggest is getting rid of the terminators heavy flamer and giving extra armour to the dread and a teleporter homer to the scouts- because your dread really needs to make it close to the enemy to have maximum effect and that armour should help him do so whilst still firing, and with the homer those 'vulnerable' scouts can bring that points heavy terminator unit directly into the midst of the enemy when they assault (or at least close enough so that the big guys dont have to slog through all that enemy firepower.
Other than that minor change I cant see much wrong with the list other than what you've already realised yourself- lack of meatshields...sorry warriors of the emperor
