Off topic but, how should sentinel scouts be armed. The emphasis in anything I read is always on autocannons or lascannons, or now a plasma cannon. The ability to move and shoot, take out tanks and terminators. Yet in the days when I played in this way the sentinels were always too fragile to stand in the gunline against tanks or autocannon equivalent armed terminators. IG guard shooting was also then as now apalling. When push came to shove a critical miss was more likely than a game winning hit. The maximum armour on sentinels was 10. A squad of bolter armed spacemarine equivalents could take a sentinel out the game with a few well aimed rapid fire shots. The special scout move seemed most useful for taking cover. And why get up close and personal when the sentinels had ranged weapons.
Nothing has changed with the new aroured sentinels. Heavy flamer is still best. The extra armour gives greater survivability. What do you think autocannon or heavy flamer. Range attacks or close and personal?
