As Barueel allready told rotation but playstyle varies with people.
basic rotation:
TB->CC->TC->DS (DS is not really hard hitting ability but is good vs some classes, i even use it as second ability in rotation for example vs slayers)-> Mutate to Brutality-> Guillotine ->(If target is not at 50% or lower, use Guillotine after these) Pulverize->Impale->Mutate back to Savagery-> repeat.
I also use Gut Ripper whenever possible because of its high dmg and its buff make you crit next ability 100% if target is not protected with anti crit such as Absolute Preservation.
Touch of Instability is great vs WPs or casters.
Debiliate is snare so use it when need target snared. But try to throw it in rotation, and always after TB.
There is other decent abilities to use, but mostly it is conditional, and varies of situation, enemy classes and numbers.
Some prefer using Feeding on Fear tactic for extra crit. It is good but you wont need it if you have high enough crit.
I also use Subvert Strenght tactic when fighting outnumbered badly and there is chosen or zealot buffing strenght ( disable Brute Force for it)
Buff Mutated Aggressor and Ferocious Assault often as possible.
Iv played with many very good marauders and many play totally different. One is never mutating to Savagery, and setting skills right so you wont hit cooldowns.
Find your playstyle and see what suits you the best, but keep the rotations for best result.
