I got one of our new players to playtest a Vanguard.
In our combat with a crocodile (I was the GM by the way), the Vanguard did more damage than everyone else. Plus he hit a fellow member of the team. They complained a lot about security, as they were at a tropical resort on Planet Raptoria. We weren't playing in the Pact Worlds, but in a homebrew world system.
Some notes:
--- The player enjoyed having entropic strike as an at will ability. We didn't fuel the entropic strike with entropy points.
--- The Vanguard dealt the most damage out of all the players. Dealing an average of 4.5 points of damage every round.
What was the rest of the party?
One Operative. One solarian. One engineer.
The rest of the party is made up of these three.
