We created a small crew of Mercenaries (1 Fighter, 1 Rogue, 1 Archer-Ranger, 1 Wizard and 1 Ranged-Cleric) and playtestet it but without real ropleplaying since the real campaign starts next week. I play the Dragonborn Fighter.

Now I am looking for two things:

1) How to best use the Fighter Marking and OA Features
Marking worked quite fine, even though I often forgot to use my bonus attack, but the theoretically awesome OA Features never came up (move stopping, Wis-Bonus). So are there any Fighters out there who can help me to maximize their benefit?
