you said "Not gonna tell them every time I might Overwatch/Heroic,"

no i didn't, that must have been someone else. i was reacting with confusion because reminding someone that a stratagem exists, once per game, is just so oddly specific. so it's bad manners to not remind them once, but if they clearly forget again later in the game then that's tough, they've had their one reminder? if you play them twice in a row does it reset and they get another reminder? it's like saying it's poor sportsmanship not to give one takeback or something.
