Scout bikers are pretty great right now.
Last edition I would run more with more upgrades too, I have thought long enough about this yet.
In your list I would run one squad with the MotF
on a bike with maybe his gun, or I would be happy to have his harness.
Meltabombs would be useful but as I say I want to think about upgrades before giving advice.
Not many people have actually run scout bikers, with politeness they didn't die easily last edition, and they are now t5 with jink.
I would go for 2TLautocannon on a couple of the dreads. This way they know their job, also they will be your main antiaircraft gun.
I would have drop pod with some melta, or at least something that can land and put the hurt on tanks. dread with MM
is cool for this, else assault cannon or tac
. squad with melta and combimelta can take a couple of shots first turn.
I would bring Telion, as he has stealth, and probably more snipers to join him.
I am not sure about all the tactical squads, you definitely need a good number of scoring units though.
Personally I would drop one tactical squad, and give the other a razorback. I personally need to have a few games with foot slogging tactical squads, they seem a very reasonable idea. Maybe on another note, you could always bring bikers as troops, they are looking great right now.
