Here's the thing. I can almost guarantee that my commando on almost any given warzone, in mostly unaugmented battlemaster modded rakata will outdamage my almost now full war hero, fully augmented shadow.
But my shadow is the one who can really contribute to wins. My shadow can pressure off nodes, solo guard nodes and stall long enough for reinforcements to arrive, throw out decent protection, pull people into the fire, run the ball if needed (not preferred) and just in general do all the little things that turn the tide in a warzone. My shadow can be a difference maker. My commando can get high damage numbers in a warzone my team could have won being a man down.
Damage means a lot, but it isn't everything.
Sorry I meant to include a high objective points too while still coming in top 3. Though we all should be able to pull out damage and still focus objectively.
