I have used tac squads in drop pods alot and I find if they are going to be going in close to the opponent, (assuming they are as they have melta) then heavy weapons in these squads are nearly useless, you cant shoot the them when they land unless you snapshot and if you survive the drop you want to be moving not remaining stationary.
Suggestions for improvement:
- Drop Multi Meltas from D.P units
- Change a Librarian to Vulkan
- Find additional points required by dropping a scout squad
Vulkan will make ur melta more efficient and he is very good assault HQ. So although ur losing ur Heavy melta the remaining ones will be TL.
Hope you got some ideas from this.
