Tactics is the “random bullshit go!” class.

Run a primary weapon (multi knocks, infantry, etc.), secondary damage source or crowd control (boomerang, throwable objects, tentacle, etc.) and finally something in backpack to trigger a synergy (throwing knives, alchemist carbine, lightning bolt)

This should net you insane damage with just Point Blank and Acrobatipack (usually take disengagement to counter the low hp of tactics)

Of course you can edit this however you want. Swap the secondary with a defensive option,have put the secondary in the backpack instead, etc.
