I currently work on a marine tactic around the dropheal from Gabe. So i need Gabe for his presence doctrine and i need kill team as droppod for free. So only place for one other elite.
Its the choice between ranged terminators and Solaria. Both work mostly the same "ranged dps elite with AoE-Ability" so it most decide on the doctrine.
Solaeia give my tacs the options to shoot on move, while termis remove the setup time from heavy bolter devastarors.
What do you think what is the bether choice?
