Got in a quick game tonight, testing 15 pts of Convergence against 15pt of Trolls on Vassal. I was running:
It wasn't pretty. I ceded going first, and he got up onto some elevated terrain. Behind the rock wall, and elevation, Gunnbjorn was extremely difficult to hit. I pegged him, but not enough to kill him. I tried for the assassination via range, and failed. For my efforts, he put a rock wall behind Syntherion, blew him into it with Explosivo, and then did very nasty things to the Cyriss caster with the bomber.
Fun quick game though.
