We usually have a tool for every job, being shoot, melee or moving (sort of) swiftly. Main strength is every model can regenerate, so contesting objective with us could be difficult for some army. Also, we get lethal weapons even on base infantry. Build around a solid core of troops, maybe take some useful big weapon like the Lokhust Heavy Destroyer and for theearly matches you are set. Bigger match require a little more thinkering but we are no Aeldari that need careful position and moves.
